Q: When was the VCS/2600 first released and what did it sell for?
A: The earliest evidence found thus far are these ads from August 1st, 1977. The first is from Longs drug stores that appeared in The Times newspaper from San Mateo, CA. The VCS was listed for $170 ($169.88) with carts for $18 ($17.88). The second is from the San Diego Union newspaper.
Other ads found in newspapers throughout the country show prices ranging anywhere from $150 to $180, with a retail list price of $190. One ad from a Canadian paper listed it for $238.
Q: What Usenet groups actively discuss the VCS/2600?
A: There are several groups, although there is very little activity on them these days:
Most ISPs no longer support access to them, but Google Groups is one web-based option.
Q: What website forums actively discuss the VCS/2600?
Q: Where can I find games for my VCS/2600 or the console itself?
A: Besides Ebay, there are still several sources for both new and used game cartridges, such as:
Other sources for both new games, used games and consoles include:

A: The most comprehensive list is maintained in the archives section of the Atari Compendium website, which includes scans I made of some of them. Some of the best ones are:
Q: Are there any documentaries that cover the VCS/2600?
A: Once Upon Atari is a four part series exploring the early days of Atari. Produced by Howard Scott Warshaw, the series is a first hand look at Atari from the people who worked there.
Stella at 20: An Atari 2600 Retrospective is a series of documentaries from CyberPuNKs (Russ Perry Jr., Glenn Saunders, Jim Nitchals and Dan Skelton) on VHS. Both "Volume 1, Tales of Stella" and Atari" and "Volume 2, The Game Designers or One Person, One Game" are around 90 minutes in length and originally sold for $25 each or $40 for both (+ shipping). The videos were never released on DVD, but the raw footage from the gathering was finally released.
Two videos - one documenting the 1998 World of Atari show and one documenting the 1999 Classic Gaming Expo - are available from Mark Santora (firstname.lastname@example.org) for $25 + $4 shipping each or $50 (shipping included) for both tapes. Contact him directly to order or to inquire about international orders or PAL format tapes.
A 4-DVD box set, CGE 2K7, documenting the 2007 Classic Gaming Expo show, is available from Scott Stilphen for $25 each.
Q: Where can I view Atari TV commercials?
Q: Where can I view Atari print advertisements?
Q: What is IRC and #RGVC and how do I get on them?
A: IRC is Internet Relay Chat, a global real-time chat network. #RGVC is the rec.games.video.classic newsgroup channel. You can download an IRC client from www.mirc.com, and you will also find some general information and instructions there.
Q: What does the Atari symbol represent?
A: The Atari symbol was designed by George Opperman in 1972. Pong was very popular then, and the symbol was a stylized version of a capital 'A', with the two opposing video game players representing the sides, and the center of the Pong court in the middle.
Q: What does the word "atari" mean?
A: The word atari comes from the game of Go, perhaps the world oldest board game. Nolan Bushnell described it as a polite way of saying you're about to be engulfed. Several early 80's magazine references define atari as, "You are about to be engulfed". Some sets of rules (such as the Japanese and World Amateur Go Championship) define it as, "A group of stones is in atari if it has only one liberty left." For more information about the game, check out the American Go Association.
Q: Where can I find Atari-like fonts?
A: The most common Atari VCS/2600 font type is Bimini. True Type Fonts (TTF) for it can easily be found online for free.
Q: Which shows, events, or gatherings cover the VCS/2600?
Q: What's the story about Atari being sued for not having a chess game?
A: There were 2 different boxes for the original VCS model in 1977. 6 artwork photos were changed between them:
The reason for why the artwork was changed is related to a story about someone in Florida who sued Atari for having a picture of a chess piece on the box when Atari didn't offer a chess cartridge:
The story has its roots in an article that appeared in the March 1983 issue of IEEE spectrum that featured quotes from then-VP of the VCS Development group Larry Kaplan and head of Engineering Allan Alcorn:
|"When the VCS was first manufactured," Mr. Kaplan recalled, "the box had a chess piece on it. 'Those marketing guys! Come on,' we said. 'It'll never do chess.' Well, some guy in Florida sued because there was a chess piece on the cover and we didn't have a chess game."
A year later Atari's designers began developing Chess. "The guys were playing around," Allan Alcorn, then head of engineering at Atari, recalled, "and one guy said, 'I could write an algorithm, but I couldn't get a playfield on the screen.' Another guy said, 'That's easy.'" Larry Wagner wrote the algorithm; it took him two years with the help of national chess champion Julio Kaplan. Mr. Whitehead did the display in two days, developing the trick now known as Venetian blinds.
The lead designer of Atari Video Chess, Larry Wagner, once mentioned the cartridge was developed as a result of this lawsuit, but later recounted his statement and said its development started as an interesting R&D project, and referred to the same IEEE spectrum article:
|To set the record straight, the chess algorithm started on a microprocessor system with 128 bytes of RAM. The best source is the IEEE spectrum article in the 80's. It was not because someone threatened Atari with a lawsuit; the chess cartridge was developed because we wanted to have an interesting R&D project.|
Bob Whitehead, the person responsible for developing the display, had this to say:
|One of the corporate reasons for doing chess I heard repeated to me several times was that we needed to do 'a chess game' because it was in some of the original VCS/2600 artwork, I think even the box itself. So, 'Atari’s committed to doing it.'|
The fact that artwork for games that Atari didn't have at the time (chess, tic-tac-toe, casino games) were quickly removed from the box, which gives credence to the lawsuit story. Atari probably felt the less people that knew about the lawsuit the better, and simply didn't tell the programmers the complete story as to why they needed a chess cartridge. By the time the IEEE spectrum article came out in 1983, it hardly mattered.
Q: What are those black lines I see along the left side of the screen in some games?
A: The black lines are the result of using a programming trick developed by Larry Kaplan that uses what's called an HMOVE command. If an HMOVE is initiated immediately after HBlank starts (which is the case when HMOVE is used as documented), the [HMOVE] signal is latched and used to delay the end of the HBlank by exactly 8 CLK, or two counts of the HSync Counter. This is achieved in the TIA by resetting the HB (HBlank) latch on the [LRHB] (Late Reset H-Blank) counter decode rather than the normal [RHB] (Reset H-Blank) decode. The extra HBlank time shifts everything except the Playfield right by 8 pixels, because the position counters will now resume counting 8 CLK later than they would have without the HMOVE. This is also the source of the HMOVE 'comb' effect; the extended HBlank hides the normal playfield output for the first 8 pixels of the line:
Here's an excerpt from an article that appeared in the March 1983 issue of IEEE spectrum, explaining what led to its development:
|One critical MOS-dependent feature was the use of a special counter - called a polynomial counter, or pseudorandom shift register - instead of a true binary counter to determine object positions on the screen. A polynomial counter occupies one-fourth the silicon area of an equivalent binary counter, but, unlike a binary counter, it does not count in any simple order. Thus, a programmer cannot calculate a screen position for an
object and load it into the position counter.
The original Stella prototype had only one signal to the position counter: a reset that would trigger the immediate display of an object. Mr. Decuir and Jay Miner, who designed the production version of the Stella chip, used this same concept in their design. As a result, displaying an object in a given position on the screen requires that the programmer count the number of clock cycles taken by a given set of instruction, figure out how far across the screen the electron beam would be after the instructions had been executed, and act accordingly. Once the position counter for an object is reset at the proper point, it continues to display the object at that spot on succeeding lines.
To move objects, the prototype blocked out four clock pulses from the position counters during the vertical blanking interval; a programmer could then add pulses to move an object left or right - four pulses had to be added to keep the object in the same place. Mr. Miner added a set of motion registers, which add or subtract pulses automatically when a signal - called H-move - is sent by the microprocessor. The H-move can be sent during the vertical blanking interval, or during the horizontal blanking interval at the beginning of each line.
"This seemed innocuous enough," said Larry Kaplan, the first software designer hired to develop games for the Stella project. "But I discovered early that it was possible to reposition player objects during a screen [a frame of the TV picture], though that was not a consideration of the design."
So Mr. Kaplan designed Air-Sea Battle, which has horizontal bands of player objects, a technique used in countless VCS games, including Space Invaders, Freeway, Asteroids, and Football. "Without that single strobe, H-move, the VCS would have died a quick death five years ago," said Mr. Kaplan, now vice president of product development at Atari.
Activision got around this by using the trick on every scanline, which effectively blacked out the screen area where the lines appear. Eric Del Sesto of M Network also used the same method that he called "hidden V-clocks". From Sesto:
|The Atari 2600 had no video memory. Instead, the CPU had to write each line of sprite data out to a set of hardware registers, in close synchronization with the video display's horizontal retrace timing. One unfortunate side-effect of this was that the hardware would display what looked like a random set of short, black, horizontal lines near the left edge of the display. The M Network group had an accepted workaround for this, which would cause those lines to appear on every scanline, thereby forming a solid black border at the left edge of the display. My Monkey Business prototype demonstrated a method to eliminate those lines completely. The trick was to write to certain registers in exact synchronization with the horizontal retrace timing.|
Q: Why do some of the early games automatically end after a certain amount of time?
A: After checking manuals for most of the early VCS titles, 4 were found to have a 2:16 minute time limit:
These games end using different time limits or rely on scoring limits:
Scott Stilphen asked 3 of Atari's early VCS/2600 game designers on how 2:16 came to be used. Here's their replies.
|This is a question whose answer dates from 1976 or 1977.
There would be two parts:
- why have one?
- why this number?
Having a time limit at all applies to some games but not others. E.g. Video Olympics will end on score. Some games end when the player uses up too many resources, or achieves some goal. Some games (like Combat) could go on indefinitely, or until a certain amount of damage was taken.
I suspect that this was common in some Arcade games.
2:16 = 136 seconds = 8160 display frames ~ 8192 display frames. That is 2^13. Some arcade game probably used a binary 13 bit counter, and the practice followed.
|Here's the comments from Combat's source code that describes it:
; GameTimer is incremented and SelDbnce reset when
; CLOCK & $3F = 0. This occurs 1 frame out of 64 or
; about once/second. Thus the game is 128*64 frames
; or about 2 minutes long.
128*64 = 8192 frames / 60 fps = 136.5 seconds = 2 min 16 seconds
Yes, we always minimized code and cut corners so it was easier to do 64 frames than 60. 4 min 32 seemed too long, so we started timer at 128 and inc'ed until 0.
|8196 frames or (8196/60) 2 to the power of 13 divided by 60 is equal to approximately 136.5 seconds. It was an easy equivalent to 2 minutes using a simple base 2 digital counter. It means if the programmer needs 2 minutes, it's cheaper in code to just use a 13 bit counter. You will see this approximation to minutes throughout all the games (i.e., 68 seconds instead of 60). Programmers were disparate for program bytes and saving a dozen program bytes was critical sometimes.
Two things to note:
1.) Atari 2600 frames are not exactly 1/60 of a second (it has to do with not using interlacing half lines and the system's digital clock speed).
2.) More importantly, 2 minutes are kind of a standard player attention span per level that was understood from the coin op days and propagated by the 2600's "casual" short attention span style games. "2 minutes" has its roots in the coin op arena.
Q: Why do some some games exhibit color-cycling if left on too long, and others don't?
A: The color-cycling is an early example of what's now called a screensaver. Systems prior to the VCS/2600 had a nasty habit of burning-in people's B&W TVs with game graphics such as scores and boundary lines. The VCS/2600 offered protection from burn-in damage by slowly cycling through all the 128 possible colors. Contrary to popular belief (due to how Atari marketed this feature), the color-cycling is not built into the hardware; it's a code routine that was written by Joe Decuir. All the system manuals up to 1984 (except the 1982 manuals for some reason) include the following statement:
"Your Atari 2600 Video Computer System game is engineered not to show a phosphor memory of the playfield or score digits."
The Sears Tele-Games manuals have a slight variation to this:
"Your Sears Cartridge Tele-Games System Video Arcade is engineered to help eliminate phosphor memory of the playfield and score digits."
Most of Atari's VCS games in the first few years immediately go into color-cycling when powered up. Basic Math was the first to have delayed color-cycling (after the game has been idle for a few minutes). Some early games (Blackjack, Casino, Basic Programming, Adventure, Maze Craze, Stellar Track don't color-cycle at all, which is surprising considering including the code for it should have been a requirement.
Q: What scores were needed to earn an Activision patch?
A: Digital Press has a section that show pictures of the patches as well as the scores needed to earn them.
Q: What was the SwordQuest contest? What happened with the prizes?
A: The SwordQuest Challenge was conceived by Tod R. Frye, and originally was called the Adventure Series. It encompasses 4 separate games: EarthWorld, FireWorld, WaterWorld, and AirWorld. Each game was to have its own contest, and the prizes were each valued at $25,000 (although the first 2 were worth a bit less at the time they were awarded).
The series was to culminate in 1984 with the winner from each of the 4 contests facing off for the grand prize: the $50,000 SwordQuest Sword. From Howard Scott Warshaw:
|We were driving back from a brainstorming session in Monterey. Warner had just bought D.C. Comics and we were going back-and-forth talking about getting a comic book series tie-in with D.C. Tod Frye did all the designs, with the four elements and how to tie everything together, which added up to about $200k worth of code! It was a cool concept, but early on though I felt that it wouldn’t come together the way we imagined.|
Each game represented one of the 4 Symbols of Astrology:
Earth (directed will - energy radiating out from the center; action)
Fire (physical - force that holds the atoms together; practical applications; consolidation)
Water (intellect; the energy that shapes the pattern of things to come; communication)
Air (soul, emotions; power of the unconscious mind; connecting to the source; reception)
The games and contest were promoted heavily by Atari's own Atari Age. The first 2 games, EarthWorld and FireWorld, were released, and the contests were held and the prizes awarded. The 3rd game, WaterWorld, ultimately fell victim to the infamous industry "crash"; it only saw a limited release, as it was initially only available through the Atari Age (copies eventually reached store shelves at the height of the crash, and priced at only a few dollars), and the contest was delayed and eventually cancelled. The programming for the 4th game, AirWorld, was started but never completed.
As for the remaining 3 prizes, it has long been rumored that the SwordQuest Sword (and possibly the prizes for WaterWorld and AirWorld) ended up in the hands of Jack Tramiel. The person who first posted this story personally saw the sword hanging over the mantle of Tramiel's fireplace, and noted it had an Atari “fuji” symbol on it, although the only artwork to depict that was the EarthWorld pamphlet. All the other artwork is identical to the only known photograph of the sword (from the FireWorld contest). It's possible the Atari symbol is only on one side of the handle. There are also those who (recently) claim to have spoken with either Jack Tramiel or his son, Leonard, with both claiming Jack did not have it. While Jack may not have had it by that point, neither Jack or Leonard confirmed or denied that he ever had it, and any claims that Warner kept the prizes during the transfer of ownership of Atari to Tramiel are completely unsubstantiated rumors. The current belief is the sword still remains with the Tramiel family. Hopefully one day the truth will come out, and with it, full disclosure of what happened to the remaining 3 prizes.
I wrote an in-depth article about the contest, called SwordQuest Revisited.
Q: Are there still VCS/2600-related contests being held?
A: Yes. The following sites maintain active contests and high score challenges:
Q: What's the myth about Atari's E.T. game?
A:There are several. One is Atari made more copies of E.T. than there were systems in circulation. Another is that the game was so bad (often cited as the "worst Atari VCS game of all time") and sold so poorly that its failure led to the infamous market crash of 1983-84 and to Atari's demise. Yet another is that so many people returned the game to where they bought it that Atari was stuck with millions of carts and ultimately dumped them in a landfill. Actually none of these are true.
In the fall of 1983, Atari decided to clear their excess stock of unsold games from their warehouse in El Paso, TX. Knowing they couldn't dump the product onto the market like smaller 3rd-party companies were doing (such as Data Age selling their games to Kandy Man Sales, who resold them to distributors for a fraction of their original worth), they instead labeled them as being faulty and chose to dump them in a landfill in Alamogordo, New Mexico, in a hasty effort to write-off the inventory. Games were trucked there in late September 1983 from Atari's El Paso, TX facility 90 miles away. Different accounts of the story have anywhere from 8 to 24 truckloads of items being dumped:
|September 25: The Alamogordo Daily News (New Mexico) reported that Atari was in the process of disposing of a sizable amount of inventory at the local landfill, and that "eight 18-wheeler truckloads (of games) have been crushed and buried in the pit since operations began."
September 27: The Alamogordo Daily News (New Mexico) reported on the local landfill and "the dumping of 11 semi-trailer truckloads of Atari computers, cartridges, and assorted parts from an El Paso warehouse in the dump since last Thursday." Atari spokesman Bruce Entin said Atari was sending scrap merchandise to the Alamogordo dump, and said, "I won't tell you there may not be some of that stuff that's good in the items sent to Alamogordo, but most is not. The majority of the stuff is cartridges."
September 28: The New York Times article reports "With the video game business gone sour, some manufacturers have been dumping their excess game cartridges on the market at depressed prices. Now Atari Inc., the leading video game manufacturer, has taken dumping one step farther. The company has dumped 14 truckloads of discarded game cartridges and other computer equipment at the city landfill in Alamogordo, N.M. Guards kept reporters and spectators away from the area yesterday as workers poured concrete over the dumped merchandise. An Atari spokesman said the equipment came from Atari's plant in El Paso, Tex., which used to make videogame cartridges but has now been converted to recycling scrap. Atari lost $310.5 million in the second quarter, largely because of a sharp drop in video game sales."
InfoWorld August 6th, 1984 article (pg. 52) reported "Twenty truckloads of games, VCSs, and home computers are found in a dump. Atari says they are defective, but critics say Atari is tossing inventory it can't sell."
The local media picked up on the story when people started sneaking into the landfill at night and scavenging games. Atari sent a security guard there and paid to have the games covered in concrete to prevent any further theft, which only brought more attention, because why would Atari bother to do that if the games were as faulty as they claimed? Well, the games weren't, and it wasn't long before the national media picked up on what was happening there, and with Atari in general. Over the years, the story of what happened was twisted to the point where the only game that was dumped there was E.T., and there were millions of copies of the game. This was coupled with the misconception that the failure of E.T. was such that it was the main reason for the market crashing and Atari's eventual demise. The fact is, there are FAR worse games for the VCS than E.T., and even with all the negative attention it received, it still ended up being the 8th best-selling VCS game Atari made (plus Atari actually re-released it in 1986).
On April 26th, 2014, a 5-man team of archaeologists who call themselves the "Punk Archaeologists" were partially funded by MicroSoft and Fuel Entertainment to excavate the site at the Alamogordo, NM landfill to prove or disprove games were actually dumped there. A documentary team headed by director Zak Penn filmed the excavation and everything that was found, with the purpose of releasing a documentary film exclusive for XBOX 360 and XBOX ONE owners. As expected, boxed copies of at least 33 different games were found, along with some common controllers:
The Punk Archaeologists released an article on The Atlantic website on August 7th, 2014 with details about the excavation, although their claim of there not being a concrete cap over the buried items is incorrect. Credit the documentary team for tracking down James Heller, the former Atari manager who arranged for the games to be dumped there, who confirmed there were a total of 12 truckloads (totaling approximately 750,000 cartridges) and that 6 concrete trucks were used. A recent Yahoo article includes comments Mr. Heller, who gave a more accurate number for how many games were dumped there:
|The game's finding came as no surprise to James Heller, a former Atari manager who was invited by the production to the dig site. He says in 1983 the company tasked him with finding an inexpensive way to dispose of 728,000 cartridges they had in a warehouse in El Paso, Texas. After a few local kids ran into trouble for scavenging and the media started calling him about it, he decided to pour a layer of concrete over the games.
"I never heard about again it until June 2013, when I read an article about E.T. being excavated," he remembers. He was not aware of the controversy and never spoke out "because nobody asked."
The article also recounts stories from one of the people who scavenged games from the landfill back in 1983:
|Among the watchers was Armando Ortega, a city official who as a teenager back in 1983 got a tip from a landfill employee about the massive dump of games.
"It was pitch dark here that night, but we came with our flashlights and found dozens of games," he said. They braved the darkness, coyotes and snakes of the desert landfill and had to sneak past the security guard. But it paid off as they found dozens of crushed but still playable cartridges.
Q: What's the infamous video game market "crash" that happened?
A:Often referred to as the big "shakeout" by publications at the time, the market crash is often falsely attributed to Atari’s VCS E.T. game, so it’s impossible to talk about one without talking about the other. As previously explained, E.T. was hardly the sole factor for the crash; the reality is the seeds for it, as well as Atari’s own demise, had been sown years before.
After 4 years of managing Atari and struggling to grow the company and expand into the home consumer market, Nolan Bushnell decided to sell the company. With the sale to Warner Communications, Inc., a company founded by Steve Ross the same year as Atari, 1972, Bushnell at last had the financial resources to successfully launch a product like the VCS. But with Warner, Bushnell also found an enemy with Warner Executive VP Manny Gerard. Gerard had a major issue with the amount of money Atari spend on R&D, and what little marketing they did for the products they sold. As Ray Kassar rose up through the ranks, both he and Gerard began to cut Atari's R&D while aggressively expanding Atari's marketing. Bushnell and Atari co-founder Joseph Keenan found themselves constantly fighting with Gerard and Kassar over the future of Atari, and slowly being marginalized and pushed out of the company. Before resigning from the company he helped start, Bushnell had contentious board meeting with Atari's new executives concerning the direction the company was headed, and in particular the fate of the VCS, which devolved into a shouting match with Gerard. The system wasn't selling as well as everyone had hoped, and Bushnell wanted to discontinue the system and focus on the development of the next generation console (what ultimately became the 400/800 computers). Gerard's hired Raymond Kassar, an ex-marketing VP from Burlington textiles, to help with establishing the VCS, replacing Bushnell as Chairman, mainly to give Atari a corporate structure; as compensation, Gerard offered Bushnell the position of Vice-Chairman, which Bushnell balked at.
Soon after Nolan Bushnell left the company, Kassar soon proved he was the wrong person to lead Atari, and his lack of compassion and understanding for what the company’s engineers actually did there began to trickle down through the company’s ever-increasing layers of management. One of Kassar's first decisions as Atari's new CEO was to cancel all the contracts Bushnell had established with all the different chip manufacturers; the idea behind the contracts was to establish a 'monopoly' for the VCS, thereby shutting out any potential rivals from releasing a competing system. Not recognizing the brilliance behind Bushnell's idea, Kassar instead saw it as a waste of money and terminated the contracts, thereby handing this bonanza of next-gen processors over to Atari's competitors. From Nolan Bushnell:
|"When I sold the company to Warner and after I left, Ray Kassar looked at it and said, 'Bushnell is a real idiot, why does he have five different chip manufacturing projects going along?' He cancelled all but the best ones. One went to TI, one went to Bally, and one went to Mattel. All of a sudden, with the stroke of a pen, he generated three major competitors."|
Even though the VCS was less than a year old by the time Bushnell left Atari, it was clear this was a product that had the potential to be very successful in the near-future - especially to those programming games for it, who soon realized their efforts were largely responsible for its initial success. Some time in 1979, four of the original VCS programmers - David Crane, Bob Whitehead, Alan Miller, and Larry Kaplan (dubbed the “Fantastic Four”) – became keenly aware of their efforts (thanks to a memo circulated by Marketing), and approached Kassar with a contract proposal that would provide programmers with designer credit on the packaging and royalties for their games. Being Atari was owned by Warner, an entertainment company, they felt they should be treated accordingly, as any other creative artist (musicians, actors, comic artists, etc). Kassar dismissed them, replying, “I've dealt with your kind before. You’re nothing than a bunch of towel designers. You're a dime a dozen. You're not unique. Anybody can do a cartridge.” From David Crane:
|“In spite of Warner’s management, Atari was still doing very well financially, and middle management made promises of profit sharing and other bonuses. Creative people don’t like to be lied to, and there was a revolt with many people leaving and others threatening to go. Job satisfaction in the whole engineering department was at an all-time low. At the same time, a memo was circulated from the marketing department showing the prior year’s cartridge sales, broken down by game as a percentage of sales. The intent of the memo was to alert the game development staff to what types of games were selling well. This memo backfired however, as it demonstrated the value of the game designer individually. Video game design in those days was a one-man process with one person doing the creative design, the storyboards, the graphics, the music, the sound effects, every line of programming, and final play testing. So when I saw a memo that the games for which I was 100 percent responsible had generated over $20 million in revenues, I was one of the people wondering why I was working in complete anonymity for a $20,000 salary. When we looked closely at that memo, we saw that as a group we were responsible for 60 percent of their $100 million in cartridge sales for a single year. With concrete evidence that our contribution to the company was of great value, we went to the president of Atari to ask for a little recognition and fair compensation. Ray Kassar looked us in the eye and said, ‘You are no more important to Atari than the person on the assembly line who puts the cartridges in the box.’. After that, it was a pretty easy decision to leave.”|
An interview Kassar did with the San Jose Mercury News in 1979 that quoted him referring to Atari's programmers as, "A bunch of high-strong prima donnas" (article) only resulted in generating more animosity towards him, and some programmers responded by referring to him as the "towel czar" and wearing T-shirts proclaiming "JUST ANOTHER HIGH-STRUNG PRIMA DONNA from ATARI". Years later in a 2011 interview, Kassar would half-heartedly admit that his comment was "probably a mistake" but claim that it was a comment made off-the-record and that, "I really did all I could to encourage the programmers".
By September of that same year, the "Fantastic Four" left Atari and set out to prove Kassar was wrong. With the memo in hand, they sought out venture capital to start Activision, and it didn’t take long for word to get around on just how much money Atari was making. Activision became the world’s 1st 3rd-party software company in 1979, and the following year started releasing VCS games. Atari’s response was to sue Activision for trademark violations and theft of trade secrets (InfoWorld 8-4-80 article). An article in the June 1982 issue of Electronic Games (pg. 9) states both parties agreed to an out-of-court settlement involving a long-term licensing arrangement (reportedly to be a fixed royalty payment).
The lawsuit lasted nearly 2 years, during which 2 more 3rd-party companies entered the market – Games By Apollo and Imagic. During this time, Fairchild engineer Jerry Lawson had reversed-engineered Atari's VCS, wrote a programming manual for it, and started selling copies to anyone interested (he was involved with the lawsuit at one point, to show how it was possible for Activision to write software for the VCS without resorting to stealing trade secrets). Apparently confident it would win its lawsuit with Activision, Kassar continued to treat employees with indifference (InfoWorld November 28th, 1983). When Rob Fulop finished his excellent coin-op port of Missile Command for the VCS in late December 1980, Kassar rewarded him with a certificate for a free turkey and a letter thanking him for the contribution he made to the Atari team. From Rob Fulop:
|"I sat there, dumbfounded. I couldn't believe that I got a turkey for doing Missile Command. I didn't know a lot about business at the time. I was 23 years old. But I remember thinking, how stupid... I'm going to leave because of this, and all they had to do was give me $10k. If they gave me the keys to a car, I would have stayed and given them another 2 or 3 products."|

VCS Missile Command was released the following June and was an immediate hit with sales of 2-3 million carts. The next month, Fulop, along with 4 other people - 2 senior VCS programmers (Dennis Koble and Bob Smith), Mark Bradley (national accounts manager), and Bill Grubb (VP of Marketing and Sales) - left to found Imagic. And yet, Kassar still refused to budge on his policies. After Bushnell was ousted and Kassar personally sought to have Space Invaders licensed, Atari's net worth skyrocketed, which no doubt reinforced his belief that his leadership was driving the company's success, when in reality he was simply in the right place at the right time. And although he re-invested heavily in the company's R&D (who created some truly innovative products like the Cosmos handheld) he had no interest in releasing anything they created; all he could see at that point was the runaway success of the VCS, and he was determined not to change course.
By the start of 1982, the Atari VCS was the ‘king of the hill’, having captured some 80% of the home video game market. The first magazine devoted to covering video games in the U.S., Electronic Games, started in late 1981; there would be a half-dozen new magazines a year later. Consumer demand was so high that people would buy just about anything, regardless of quality. The 1981 holiday season was such a huge success that many distributors ran short of product, having failed to order enough; Atari's response was to force them to preorder everything for the entire year of 1982. Distributors, not wanting to be caught short again, were forced to play Atari's game. In February 1982, Tod Frye went to his manager, George Kiss, and informed him that both he and Howard Scott Warshaw were approached by 20th Century Fox to start up a new game company. At that point, Kassar finally realized that with them gone, Atari would have no senior VCS programmers left, and capitulated in giving the engineers both royalties and credit for their games. Convinced that porting arcade games to the VCS was the most-profitable course of action after the huge sales for Space Invaders, Asteroids, and Missile Command, Atari aggressively went after obtaining the license for Namco's Pac-Man. Tod Frye, given the choice of porting either Defender or Pac-Man to the VCS, chose the latter. By the time it was released, Pac-Man was the most-popular game in the world, and Atari's Marketing department went into overdrive promoting the fact they had the exclusive home cartridge license for it. Atari wildly over-produced the game, making 12 million carts, at a time when the installed user base was approximately 7 million. They were hoping for another "Space Invaders" effect of a game driving system sales to pick up the surplus, and to some extent it worked; nearly 8 million cartridges were sold at an astounding $37-$45 each, making it the best-selling VCS cartridge ever, and Atari ended up selling some 5 million consoles that year. The most-anticipated cart release of 1982 also helped programmer Tod Frye earn a reported $1 million in sales royalties, since we can pretty much rule out "word-of-mouth" helping sales of what was soon considered to be not only a bad knock-off, but one of the worst arcade ports ever done. Only years later did the world learn Tod was given a mere 4K to program it (instead of the 8K he requested), resulting in many liberties being taken - Pac-Man only looked left or right, monsters became flickering ghosts, fruit condensed into a single "multi-vitamin", dots ballooned into large "wafers", energizers became power pills, etc. The garish sounds and colors only added to the nightmare. By the time 8K was offered to him (as Rob Zdybel claims, although Tod claims he was never offered it), the game was nearly done, which would have meant starting over. However, Atari never fully recovered from their decision to release it (and in the quantities it did) and the scathing criticism that followed. Next to technologically-superior consoles like the Intellivision and Colecovision, the VCS looked very much like the 5-year-old, 1970s dated technology it was. From Tod Frye (Next Generation, April 1998, pg. 41):
|"A while after Pac-Man was released, Ms. Pac-Man was developed with an 8K ROM by a three-man team in six months. The first Pac-Man was developed with a 4K ROM by just one man in five months. This 4K ROM was the big problem (Ed.: In subsequent comments, he said RAM was the big problem). My version also included a two-player mode and this drastically ate into what little ROM there was. After the release of the game, Atari set a new rule that
every game needed to have an 8K ROM.
Why wasn't the project allocated better resources? At the time the project was started, 8K ROMs weren't available yet (Ed.: Not True. Asteroids was 8K and came out the previous summer and the bank-switching scheme was developed 2 years prior to that, for Video Chess). Also, when we started doing the port, Pac-Man wasn't a particularly big game. 'Pac-Man fever' hit between the start and the finish of the project (Ed.: Pac-Man was already very popular by the time Frye started programming his version, which would have been summer 1981. Both Coleco and Entex had their hand-held versions out later that year, and Magnavox released K.C. Munchkin for their Odyssey2 by January 1982).
A video from the 2015 Portland Retro Gaming Expo shows Tod commenting on a new VCS version of Pac-Man and exclaiming he never understood why his version got so much criticism for the different maze layout, and for having the tunnel exits on the top and bottom, instead of on the sides like the arcade version. He also commented (in the Stella at 20 documentary) that he would have had a better flicker management routine had he had enough time to finish it (?), but he also claims he had a kernel working that used the same anti-flicker management system (using vertical separation and variable flicker) that Ms. Pac-Man used, but decided not to use it because nobody else had (?). In a keynote from the same show, Tod states he wish he had made a black background with a blue maze, but claims Atari had a rule against black backgrounds because it would have burned the maze into the CRT (apparently this rule didn't apply to space games...). This makes no sense since Atari touted the anti-burn-in effects of the VCS from day one, plus Tod included the color cycling code routine in his Pac-Man game! I've also asked several VCS programmers - including Tod's Manager at the time, Dennis Koble - and nobody else recalls there ever being a rule or even a guideline regarding the use of black backgrounds. So Tod's unfounded claim appears to be nothing more than an excuse for his poor design choices.
The success of VCS Pac-Man only fueled the public's desire for more arcade titles. Atari subcontracted General Computer Corp (GCC) to contribute porting arcade games, and new chips were designed to allow for improved versions (the following year would see GCC's amazing port of Ms. Pac-Man). In late 1982, Kassar made a weak attempt to fend off the VCS's competitors with the 5200, but the console was nothing more than a repackaged Atari 400 computer (which was originally released in 1979) with quite possibly the worst controllers ever devised, plus it wasn't compatible with either the VCS or the 400.
For most people, VCS Pac-Man convinced them the system's limitations had been reached. Whereas Bushnell wanted to effectively kill the VCS too early in its life, Kassar hung onto it too long. Still, with an installed base of some 15 million consoles, companies continued to spring up, fully intent on supplying those owners with new software. With the Atari vs Activision lawsuit settled, the path was clear for anyone to sell software for the VCS, and by the end of 1982, some 2 dozen companies did just that, though most of it was inferior. Atari didn't help matters with inferior ports like Defender and Pac-Man, or ill-conceived concepts such as the 4-game SwordQuest contest. The battle to win licenses for the most-popular arcade titles raised the stakes for larger companies who could afford to play that game, like Mattel, Coleco, and Parker Brothers. Arcade companies recognized this, and would often insist on deals for 2 or more games. For example, Parker Brothers was only able to secure the rights to Nintendo's popular Popeye game if they agreed to buy the unsuccessful Sky Skipper as well. After 20th Century Fox licensed its hottest property, Star Wars to Parker Brothers, and their failed attempt to lure away Atari's remaining senior VCS programmers, they formed their own division, Fox Video Games, and subcontracted at least 4 companies (including Sirius Software) to write games for them - some based on their movies and TV shows (Atari had been first with this approach with VCS Superman, but never fully capitalized on it). Parker Brothers struck gold with their first 2 releases: Frogger and Star Wars: The Empire Strikes Back. Determined not to miss out on another property like Star Wars, Atari quickly locked up licensing deals with LucasFilm and Steven Spielberg. They also tried a tie-in with Warner-owned DC Comics, only to realize pack-in comic books don't result in more sales. The bidding frenzy, as well as Atari's own hubris, reached their absolute zenith with Atari's E.T. game.
E.T. the Extra-Terrestrial was Atari's 2nd movie tie-in game, after Raiders of the Lost Ark, and the first bad one (in what would become a long line of). Atari paid an obscene amount of money to Spielberg for E.T., which was the most-successful movie ever at the time, and planned to have the game on store shelves by Thanksgiving, in time for "Black Friday" and the 1982 holiday shopping season. Kassar maintains he tried to convince the head of Warner, Steve Ross (who orchestrated the deal) it was impossible to delivery a game in so short a time frame, but that Ross insisted Atari had to do it. Although another executive stated when he told Kassar the same thing, he replied, "E.T. is such a hot property, whatever we put out will sell." (InfoWorld December 5th, 1983, page 146). Unfortunately, due to the deal not being finalized until late July and pressure to get the game on the shelves in time for Christmas, programmer Howard Scott Warshaw was left with an unbelievably short timeframe of 5-1/2 weeks (which meant little or no game testing was done), at a time when game development took several months. Warshaw calculated he produced game code (finished, debugged, and documented) at 13 times the industry average! An article from the Chicago Tribune, dated 11-7-1982, stated Atari planned to spend $5 million advertising the game, with Atari's VP of Coporate Advertising, Jan Soderstrom, proclaiming E.T. "Will be as big a hit if not better than Pac-Man." Not learning from their mistake with Pac-Man, Atari over-produced the game, making between 4-5 million (mainly because they needed to sell that many in order to turn a profit), and only selling about 3.5 million. Some of the unsold copies (along with Pac-Man and other products) ended up being dumped in at least 2 landfills.
On December 7th, 1982, Atari dropped their own "Pearl Harbor" attack on Wall Street and announced their 4th Quarter sales estimates were only a 10-15% increase, instead of the 50% they originally predicted. It's important to note that they weren't losing money at that point, they just weren't going to make as much! Warner's stock took a big hit after that (overall the stock market dropped 29 points in the 2 days after Atari's announcement), as did all video game-related stocks. The following day, Mattel announced they actually lost money that quarter, which didn't help matters. The day after that, Perry Odak, Atari's President of CED, stepped down, basically taking the fall for the Wall Street announcement (NY Times article); Odak soon joined Nolan Bushnell's Catalyst group (article). Imagic had planned on going public the following week, but the news forced them to withdraw their plans. According to the editorial in the March 1983 issue of Video Games (pg. 6), analysts had been predicting a "shakeout" in the video game business for about a year before Atari's announcement, and all the negative reports that followed in the months after only fueled the fears of a market crash. Still, the news shocked most analysts and started Atari's precipitous fall, as well as the industry's.
The coin-op industry was even more susceptible to the increased competition. Arcade earnings were but a fraction of home sales, but were still far below what they had been. Like home games, operators saw the same drop in 1982-83. Laserdisc games were the last-ditch efforts to sustain their earnings growth, and when that failed, most arcades closed, and operators sent many an arcade game to the dumpster.
Atari, seeing their 4Q troubles ahead and their market share dropping to 60%, tried to restructure their distribution network a month before. They had some 130-140 distributors for their products - far too many than was needed - and some started getting into price wars with each other. On November 1st, Atari told all their distributors their contracts were cancelled and that only a small number of them would be awarded exclusive contracts. Since Atari never bothered to have exclusive distributor contracts prior to then, their competition simply used the same distributors. Those who were forced to preorder for 1982 and were later dropped by Atari simply started shipping unsold product back to them. Since Atari didn't audit the distributors they had dropped, they were forced to buy back whatever they were sent.
Nearly all of the 3rd-party VCS game companies that started up in 1982 closed down in 1983, and yet by the end of 1983, nearly 3 dozen more companies had sprung up. Seeing Activision's success, they were convinced the market would soon level off and become stable (much like how some Titanic passengers felt the ship would level off and stay afloat). At this point, there was literally a glut of product - more than there was shelf space available for them - and most of it was awful. Atari's market share fell to 40%. As these companies quickly collapsed, they gave their inventory to distributors for practically next-to-nothing, instead of throwing out their product (Atari had the right idea, but for the wrong reasons). People aren't going to spend $25-$40 for the latest games when they're next to games selling for $2, especially after being burned by the marketing hype for Pac-Man and E.T. Meanwhile, Kassar continued to invest heavily in R&D with no long-term plan on what to do with anything that was created. By the end of 1983, Warner was looking at half a BILLION in losses, and the industry had passed the point of no return.
IEEE spectrum mentioned the situation in an article in their January 1984 issue, sub-titled "Chaos in Home-Computer and Video-Game Markets" (pg. 81):
|There was considerably less optimism last year as sales slowed in the home-computer and video-game industries. Startup video-game companies proliferated in 1982, and while industry sales for video games grew by approximately 25 percent in 1983, the number of video-game cartridges produced increased by many times that amount, flooding the market. Also, consumers began moving away from the purchase of traditional video games and towards home computers. As a result, Atari Inc. of Sunnyvale, Calif., a subsidiary of Warner Communications, dumped truckloads of game cartridges in New Mexico after absorbing heavy losses (Atari said the cartridges were defective). Several recently started companies - like U.S. Games, a subsidiary of Quaker Oats; Data Age; Fox Video Games; and Games by Apollo - closed their doors. Imagic Corp. of Los Gatos, Calif., sold its inventory and cut staff: games that previously cost $30 now reached the consumer priced near $5. Even Activision Inc. of Mountain View, Calif., which held on to profit margins longer than most other companies, posted a large loss late in the year.|
From Howard Scott Warshaw:
|"Atari, for years, was using the leverage that they had to just screw distributors everywhere. When they had a hot game, they would force distributors to buy copies of the old games that weren't selling anymore, just to get copies of the new game. This is the kind of stuff they were doing. So when things started to turn on them, everyone in the industry was waiting to jump on them with both feet. That's what killed Atari - the ill will that they had generated through their cutthroat business practices on their way up."|
In conclusion, there were many factors which lead to the market crash of 1983-84:
Warner's management style clashed with Nolan Bushnell's, and led to him leaving the company. He was replaced by Ray Kassar, who had no experience with the video game industry, and was either unable or unwilling to adapt to it. His outdated management policies left Atari with no long-term plans on how to proceed beyond the products they had, and his short-sightedness/lack of vision let to competitor's consoles using next-gen processors that Atari paid to develop. He also failed in his primary task to create a corporate structure, instead choosing to run the company like an "emperor" with him having to approve every decision. Coupled with his penchant for setting people against each other, the result was an atmosphere of paranoia and fear, which led to much employee turnover, especially in Management.
Atari's engineers were the 'lifeblood' of the company. Instead, Kassar refused to compensate Atari's engineers for their efforts, viewing them as insignificant and easily replaceable, and the result was Atari ended up creating their own competition with the rise of 3rd-party software companies (whereas before they enjoyed complete control of the VCS), which led to a glut of product. By the time Atari instituted a royalty program, it was too late.
Q: What happened to Atari?
A: The Atari that everyone knew and loved (1972-1984) is long gone. In its absence, there have been a string of "imposters". The infamous market "crash" of 1983-84 decimated the video game marketplace. It impacted every company, including Atari, and by early 1984 only a few companies remained in business. Both CEO Raymond Kassar and Senior VP Dennis Groth were charged by the Securities and Exchange Commission with insider trading from selling personal shares of company stock minutes before the infamous December 7th, 1982 Wall Street announcement (New York Times article). As a result, Kassar resigned in July 1983 and was replaced by James Morgan in September 1983. In the Summer of 1984, Atari was some $400 million in debt, and on July 2nd, Warner Communications basically blindsided Morgan and sold off the home (console) and consumer electronics (computer) divisions to Jack Tramiel, the founder of Commodore, and a group of unknown investors for $240 million (Warner received no cash, but received US$240 million in long-term notes and warrants for a 32 percent interest in Tramiel's new venture. Tramiel, in return, received warrants giving him the right to purchase one million shares of Warner common stock at US$22 a share. This was basically an accounting maneuver by Ross to improve Warner's stock to stop a hostile takeover by Rupert Murdoch's. Ross had previously rejected Philips offer to purchase 100% of the company b/c he wanted to keep a stake in Atari). Between being ousted from Commodore and buying these Atari divisions, Tramiel set up his own company, Tramel Technologies, Ltd., with $75 million from unnamed investors, and renamed his company Atari Corporation with the purchase (InfoWorld August 6th, 1984 article, pg. 51-52; A History of Tramel Technology/Atari article). The coin-op division remained with Warner and became Atari Games. In December 1984, Warner sold off the AtariTel division to Luma Telecom, a division of Mitsubishi Electric (Michael Current has a website detailing the history of The AtariTel division).
THE ARCADE DIVISION:
When Warner merged with Time in 1989, a Time-Warner Interactive label appeared on their arcade games. In 1996, Time-Warner sold Atari Games to WMS Industries (the merger of Williams and Bally/Midway, when Williams purchased them in 1988), who turned around and spun off part of its Midway Manufacturing division as Midway Games. Atari Games became a subsidiary of Midway Games as a result. In January 2000, Midway changed the name of Atari Games to Midway Games West, to avoid confusion with Hasbro Interactive's Atari company. The Atari logo for home conversions of Atari's arcade games during this time appeared under the Midway Home Entertainment label. In spite of all this corporate shuffling, a few of the Atari veterans, such as Ed Logg and John Skruch, remained. Ed Logg, whose credits include the arcade versions of Asteroids and Centipede, as well as VCS/2600 Othello, was still there by the summer of 1999.
THE HOME DIVISIONS:
After taking over Atari, Tramiel immediately ceased all video game development, cancelled several projects (including the 7800 and 600XL), and fired 700 employees, as his focus was on developing and releasing a new line of home computers (BusinessWeek article, July 23rd, 1984, pg. 90-91; Electronic Games article, October 1984, pg. 14), starting with the Atari STs; the previous issue of Electronic Games had a 4-page article announcing the 7800 and at least 12 games. At the 1985 Winter CES show, Jack Tramiel stated Atari was going to change its image from that of a game company to that of a microcomputer organization, and announced no less than 7 new computers (8-bit 65XE, 65XEM, 65XEP, 130XE; 16-bit 130ST, 260ST, 520ST. ROM article, February/March 1985 V1N10, pg. 54). 1 year after the takeover, the media confirmed there were no plans to release the 7800 (Computer Entertainment news blurb, August 1985, pg. 71). 2 years after the takeover, Tramiel, seeing Nintendo's success with their NES console, decided to get back into the video game market by resurrecting and re-releasing systems (VCS/2600, 7800, 400/800/XL) that were originally developed by Atari Inc., with either a new case, a new name, or both. The VCS/2600 became the 2600 JR, and the 65XE computer became the XEGS console. Both new and unreleased games were released for all of them, but the main reason for their release was to sell off the mountains of games Atari still had in their warehouses. Some former programmers, such as Bob Polaro, were sub-contracted to either finish some of their prototypes or program new games. Once that was done, Atari decided to make a serious attempt to recapture some of the now-hot market again, buoyed by the huge success of both Nintendo and Sega. In 1989, Atari purchased the Handy handheld gaming system being developed by Epyx and released it as the Lynx, to moderate success (5 million were sold). On January 1st, 1992, the VCS/2600 was officially discontinued, along with the 7800. According to VP of Marketing Dana Plotkin, the entire inventory of games for both systems was sold to Consolidated Stores Corp./Odd Lots (a department store chain based in Ohio), with no plans to produce more; the reason given was to focus on the Lynx. In November 1993, Atari released the Jaguar game system, which proved to be the company's undoing. Hampered by poor business ethics and lack of major advertising, as well as a lack of any major 3rd-party support (a little over 100 games were made for it, over 5 years), the Lynx was eventually discontinued in 1994; the Jaguar would follow suit 2 years later. Again, a combination of poor treatment of 3rd-party developers and suppliers, as well as a lack of any serious advertising, resulted in only 125,000 Jaguar systems being sold by December 1995, with another 100,00 left in warehouses. A settlement with Sega over patent infringements gave Atari a brief lifeline of cash (Sega purchased $40 million of Atari's stock and paid Atari $50 million to license over 70 patents from 1977-1984). Both companies agreed to cross-license up to 5 games per year through 2001, but ultimately nothing came of it, and the Jaguar was discontinued by early 1996. On July 30th, 1996, Atari Corp. merged with disk drive maker JTS with more of a whimper than a bang. Former Atari alumni Don Thomas wrote ashort, insightful bit about the merger and the history leading up to it that asks more questions than it answers.
On February 23rd, 1998, JTS sold substantially all of the assets of the company's Atari Division, consisting primarily of Atari home computer games and the intellectual property rights and license agreements associated with such games (the "Atari Assets"), to HIACXI, Corp. ("HIAC"), a wholly-owned subsidiary of Hasbro Interactive, Inc., for $5,000,000 in cash. The following is a brief summary of what Hasbro got (read the entire 8-K form that was submitted to the Securities and Exchange Commission regarding this transaction, which specifically lists some of the things):
|Atari Hardware Platforms
• Atari 2600
The update of Centipede came (in small part) from the ashes of Atari Corp. Interestingly, Hasbro resurrected the Atari name and logo; many of their classic releases during that time (Atari Arcade Hits 2, for example) appeared under the Atari name (ad).
On December 6th, 2000, Hasbro entered into a "long-term licensing agreement" with Infogrames, wherein the French company acquired 100% of Hasbro Interactive (which included the Atari bits they owned - article and sales report). On October 2008, Infogrames completed its $11 million stock purchase of Atari, making it a wholly-owned subsidiary of the French publisher. In May 2009 Infogrames announced it would be changing their name to Atari, SA. In April 2010, Atari board member and former CEO David Gardner resigned, and Atari co-founder Nolan Bushnell joined the board!
In January 2013, Atari US filed for bankruptcy and planned to sell all of its assets - including the famous "Fuji" logo - in an effort to distance itself from its parent company, Atari SA (Forbes article). After approaching some 180 potential buyers (Wall Street Journal article), Atari was unable to find one willing to purchase everything, and auctioned off everything instead (Gamasutra article). Atari still exists (website), but mostly in name only and continues to peddle compilation packages of past hit games.
Q: How many different games were made for the VCS/2600?
A: At last count, there are 495 unique, original games that were officially released, not counting prototypes (202), homebrews (approx 300), or titles that were renamed or slightly altered (97). If you include all the pirate clones and unauthorized versions (well over 7,000), the grand total swells to over 8,000! And then there's the 1,000+ hacks that have been created over the years...
Q: Have any new VCS/2600 games been released lately?
A: Well over 100 new games have been developed for the Atari VCS/2600 since the mid-1990s. Commonly referred to as "homebrews", most of these can either be purchased on cartridge or downloaded for use with an emulator or to make your own cartridge. Here is a partial list of new games recently released:
Q: Where can I download game instructions?
A: Several sites offer manuals online, in text, html, and PDF formats:
Q: What are the most and least popular games?
A: This can be a subjective matter, of course, but here are some of the most popular:
Here are some of the least popular:
Q: What are the most common and most rare games?
A: The simple law of supply and demand is the biggest determining factor; the more popular a game was or the more copies that were produced back in the day, the less valuable (monetarily) a game is worth. Some of the best and most popular games are only worth a few dollars at most. It's the games from small companies with production runs limited to a few hundred or even a few dozen that are worth more to collectors, since they're the hardest to find. Other factors are the condition of the cart and the packaging, what label variation it is, and whether the cart is loose or includes the box and manual (CIB or Complete In Box), and if so, whether or not the box is sealed. Several sites offer online price and/or rarity guides, as do several books. Generally, you'll find higher prices on Ebay than you would through online message boards.
As for which game is the rarest, that game is Air Raid by Men-A-Vision. This was the one and only release from this company, which has a unique, blue, T-bar handle-shaped cartridge casing. Less than a dozen copies have been found since the mid-'90s. A boxed copy went up for sale on eBay in 2010, and sold for a staggering $31k - nearly 10x the value of a loose cart. And like most rare carts, it's a horrible game (to play). What's worse, the game is actually a hacked/pirated version of U.S. Games' Space Jockey (a game that's currently worth about $3 boxed)!
Q: What VCS/2600 software was announced but never released?
A: Atari Compendium has a list for most with photos and related info here.
Q: What was the GameLine and what games were available for it? Were there any other services like it?
A: GameLine was a service offered by Control Video Corporation that allowed you to download games to the VCS/2600 over regular phone lines via the use of their GameLine Master Module. The complete kit contains the Master Module (an 8K RAM cartridge with internal 1200 baud modem - more tech info can be found on the Stella Archive), telephone connecting cord, a duplex T-adapter, owner's manual, registration guide, GameLine membership cards, and "temporary" game directory & instructions. It originally sold for $49.95 and there was a one-time membership fee of $15. Charges were about $.10 a game or $1 for up to an hour of play. Contest games were $1 and there was a $.50 charge to enter a score. Once it connected, it downloaded the menu program to the battery-backed 2K of RAM. A title screen appeared and "Assembly of Trumpeters For Reveille (First Call)" played. Next, a screen appeared for you to enter a 3-digit number for your ID, and after that another screen where you selected the game you wanted via a 3-digit number, or you could enter 999 for a special "browse" menu. Once the game loaded, a screen would appear with both the game's name and the company who made it, and a tune very similar to the German Army WWI bugle call "No. 2 Battery" played. On your birthday, a screen would appear with the message, "Happy Birthday! All of your play today is free!" while the first 2 bars of "Happy Birthday" played. One of the game catalogs that was archived lists 76 games which included Save The Whales - a game long thought to be vaporware until it was found years later. The GameLine system became QuantumLink (also known as Q-Link), an online service for Commodore computer users, which became America On-Line, the most successful online service ever. See Dan Skelton's GameLine article for more information and a complete list of games that were offered, along with footage of it running.
2 other similar services were close to going into service at the time. One was a joint venture between Atari and Activision in 1983 called Electronic Publishing Systems (EPS). They developed the "Electronic Pipeline", a game service for the Atari VCS/2600 that was to sell wireless game cartridges with which users could select and play up to 40 different games each month for a low monthly subscription fee. A TV commercial was created for it, and the service was in alpha testing and a mere 4 days from installing the transmission equipment in the first test market when it was indefinitely postponed due to Warner's sale of Atari in 1984.
The other was "Project Zelda", a top-secret plan to distribute games online (via cable). From my interview with Steve Kranish (who designed the head end hardware):
|The basic idea was that Parker would provide a TV channel signal to cable operators that contained the multiplexed (interleaved) data for their game cartridges. Parker would sell – or the cable operators would subsidize – a special cartridge for the Atari 2600 that would plug into the 2600, and had a cable that would connect to your cable box. In the 1982-83 timeframe, the only distribution channel for games was physical hardware, and cartridges dominated the market. Someone decided there must be another way to distribute games. The chosen solution was the rapidly expanding field of cable TV. This was during the time when Beverly, MA was first wired for coax, so we had cable access available locally." The cartridge menu software worked similar to the GameLine, in that since the menu contents would change frequently, they had to first be downloaded before they could be displayed. At some point, Parker got cold feet and abruptly cancelled the project. The official reason given was Atari - being owned by Warner Brothers, with Warner being a partner in Warner-Amex Cable (a major cable TV company at that time) - must be planning to do the same thing. With their access to cable operators, and deeper pockets, there was no way that Parker would be able to compete with them.|
Steve Kranish states there might have been another possible reason:
|Zelda would have put Parker directly into the distribution business, competing with its major customers such as Toys-R-Us. As a direct distributor of (video game) content, Parker would have even been in a position to handle material from other video game producers, if it wanted to. This could have given it a very dominant position in the business. The channel was to have been used to milk a little more money from older games, and provide ‘teaser’ access to new games that would be available for a few days, and then taken off the channel for a few months, to encourage cartridge sales. But putting Parker in direct competition with its biggest customers would have been very bad for the traditional (paper) side of the business, which needed Toys-R-Us and the like as a distribution channel. So it is possible that this conflict of interests played a major role in the demise of Zelda.|
Q: Which VCS/2600 games use the Paddle controllers?
Q: Which VCS/2600 games use the Driving controllers?
Q: Which VCS/2600 games use a light gun?
Atari released the G1 light gun for use with the VCS/2600 and 7800. It's the same as the XG-1 model that came with the XEGS, except that it's orange instead of grey. Best Electronics sells their own version, called Best Atari Light Gun, which supposedly works better than Atari's own. Also, see the entry for rewiring a Sega light gun down in the "projects" section of this FAQ.
Q: Which VCS/2600 games use the Keyboard controllers, the Video Touch Pad, and the Kid's controllers?
A: All 3 controllers work the same way, and are compatible with the following games, although the overlays will only fit one type (listed after title):
Q: Which VCS/2600 games required the use of 2 controllers, or only the right controller?
A: These games required use of 2 controllers:
Most games primarily used the left joystick (for one player), but these games default to the right joystick:
Tac-Scan is the only paddle game that requires them to be plugged into the right port.
Q: Which VCS/2600 games support 3 or more players?
|G.I. Joe: Cobra Strike||3||Joystick + Paddles|
Q: Which VCS/2600 games use the system switches during a game?
Q: Which VCS/2600 games have digitized voice samples?
Q: What VCS/2600 carts do not work on the 7800?
A: There are known incompatibilities with some NTSC versions of the 7800 (PAL 7800s seem to be unaffected). Games that may not work include:
Overall, 7800s manufactured between 1984 and 1986 are more compatible than systems made after 1986. Below is a compatibility chart by James Randall that shows the testing results from 17 different systems made between 1984 and 1988. Of those, only 3 (highlighted in yellow) proved to be fully compatible:
From James Randall:
|In regards to compatibility there is nothing consistent. I did end up with 3 units that could play anything I threw at them, but having a similar unit to these is no guarantee of 100% compatibility. I used the 7800 Diagnostic cart to calibrate the color and to check for errors. I used Double Dragon to test the consoles 2-button functionality for each player. Food Fight, Dark Chambers, and Santa Simon were checked to see if they would load and play fine. All units worked
fine with Food Fight and Dark Chambers. Santa Simon did not work on 2 units and was almost playable on another.
For 2600 testing I used both cartridges "(C )" and the Harmony cart "(H)". It was interesting that using the Harmony cart gave me near 100% compatibility for all units. Another great reason to get one! For the two instances where BurgerTime did not work via Harmony, the real cart worked fine.
None of the units had problems with the real cart versions of BurgerTime, Kool-Aid Man, or Stargate.
Time Pilot was easily the most difficult cart for the 7800 units to handle, followed by Decathlon.
The Color Bar Generator and TestCart were not for compatibility but I did use them for console functionality and color calibration (2600 mode).
For the early units (EP, AT84&85), the motherboards and serial numbers did not follow any sequence. An early serial number is not a guarantee that the motherboard is an early model as well. Even my "test market" EP motherboard was made in the 24th week of 1984 whereas another unit had a motherboard made in the 21st week. I guess Atari made a bunch of motherboards in 1984 and when they were assembled into the casings then it was whatever the person on the assembly line grabbed.
Also, I did have three units with the different rainbow pattern on the front of the 7800, including my "early" EP unit. These are marked with an (*). Normally, most rainbows on the 7800 start in yellow and end in green, but few start in red and end in purple. This is cool as it corresponds to the actual visual spectrum of light (a real rainbow).
Also, my lowest serial number AT84 unit only has a hole for the expansion port but no pins. It is also made in the 27th week of 1984. This is weird as other models made in 1986 or 1987 still had the full port with pins. Maybe this was simply an error?
In addition, a 7800 system has been found (Atari Corp. serial A1 72R4BR 5154270, Rev A 3187 pcb) that doesn't run BurgerTime or He-Man using a Harmony cartridge. All the chips on the pcb were soldered. There was no Expansion slot nor any markings on the case for it. Another one I found (Atari Corp. serial A1 72RBR 5774010, Rev A 0287) ran both BurgerTime and He-Man using a Harmony cartridge. 3 of the large chips were socketed and there was an Expansion slot. Some homebrews such as Boulder Dash also have incompatibility issues with some 7800 systems.
The conventional wisdom saying that a deck with the expansion port will work with anything is false. Presence or absence of the port is not a reliable indicator of compatibility with all VCS/2600 carts.
The manufacturing standards of systems made in 1984 are better than those made later. All the major chips inside are all socketed instead of being soldered directly to the board. Some of the other decks also have had some minor factory patchwork performed. They occasionally have resistors bridging points where they were clearly not originally intended to be, i.e. soldered directly to a chip pin or placed on the underside of the board.
Q: What is the Starpath CD and can I still get one?
A: The Starpath Supercharger Game Collection on CD, or Stella Gets a New Brain was a non-profit, long-awaited labor of love from the CyberPuNKs (Russ Perry Jr., Glenn Saunders, Jim Nitchals and Dan Skelton). This CD not only contains NTSC and PAL versions of most of the Supercharger games (PAL Survival Island is missing), but also development tools, a collection of Supercharger and Vectrex material, and several surprises (including SoundX and the UR Polo from Carol Shaw). There were 2 different versions of the Starpath CD made. Some things on the first version were not included (e.g. the Vectrex stuff, Polo) while other things were added. CyberPuNKs' Glenn Saunders later donated the remaining unsold inventory to Randy Crihfield of Hozer Video Games, who sold them for $5 each. The CDs have long since been sold out, but he still has some manuals left (for $5, which include a pair of CDs). Original copies occasionally surface on Ebay. More info available here.
Q: Where can I find a list of tricks and Easter Eggs?
A: Atari Compendium maintains the most complete and up-to-date Easter Egg lists for the Atari VCS/2600, 5200, 7800, 8-bit computers, and arcade coin-op games.
Q: What programming resources are available?
Q: Is there a list of VCS/2600 game programmers?
Q: Where can I get solutions to the SwordQuest series?
A: Atari Compendium now hosts Walton C. Gibson and Keita Iida's SwordQuest Archive of Adventure, which offers the solutions.
Q: What's the story with Sears Tele-Games, and why do some games have different titles?
A: Atari's relationship with Sears Roebuck and Co. started with their home Pong system. Under their arrangement, Sears helped Atari in contacting a venture capitalist to obtain the additional funds needed to help with producing the Pong system. In return, Sears would be the exclusive distributor of Pong through the 1975 holiday season on the condition they were rebadged as Sears products. These were given the Tele-Games Electronic Games moniker. This rebadging continued with several other dedicated systems, up to and including the VCS/2600.
It's unknown why exactly this was done. Although collectors like them (Tele-Games carts - especially those complete with box and manual - are harder to find), they often end up being a source of confusion and frustration for owners, especially when they find out what they initially thought was a new game ends up being something else (and sometimes one they already own).
A total of 26 different titles were renamed under the Sears Tele-Games label. Here's the complete list:
|Air-Sea Battle||Target Fun|
|Dodge 'Em||Dodger Cars|
|Human Cannonball||Cannon Man|
|Hunt & Score||Memory Match|
|Maze Craze||Maze Mania|
|Miniature Golf||Arcade Golf|
|Sky Diver||Dare Diver|
|Space War||Space Combat*|
|Star Ship||Outer Space*|
|Street Racer||Speedway II*|
|Video Olympics||Pong Sports*|
|Video Pinball||Arcade Pinball|
* These feature different packaging artwork than the Atari releases.
A total of 58 different titles were released under the Sear Tele-Games label. Here's the complete list:
Demons to Diamonds
Math Gran Prix
Stellar Track *
Submarine Commander *
Super Breakout **
Star Raiders was the last Atari game to be published in both Atari and Sears-style packaging.
* These were Sears exclusives and were never released under the Atari label.
** The Sears version was initially released first as an "exclusive" in 1981, which means Atari probably didn't have much faith in it being popular. The Atari version was released in January the following year.
Q: Are any release dates known for the games?
A: Check out Duane Alan Hahn's website for detailed information. Here's the most complete list I have for Atari's own games. Specific release dates listed with some are those listed with the U.S. Copyright Office (LINK).

* Atari announced it as November release, but it was the first silver label sold through Sears which would put it on the shelves in late September/early October before Earthworld was released. The retail sheet I once owned showed ROTLA as a September release. A label variant of Raiders of the Lost Ark exists with a normal silver label on top, and an orange Sears-style end label. No silver-labeled Atari carts have any Sears-labeled counterparts, so this is exactly where the Sears label variants era ended.
A Sears manual for SwordQuest EarthWorld also exists, which is owned by former Atari technical writer John-Michael Battaglia. This may have been a one-off, as no Sears EW carts have ever been found.

Q: Are there any sales figures for the games?
A: Once Upon Atari showed some documents (in the "Agony & Ecstasy" episode) that listed some cartridge sales figures:
Q: How many VCS/2600 systems were sold?
A: Here's a rough timeline based on the available info (below)
Chart from the March 1983 issue of IEEE spectrum, page 50.
1978 500,000 = 750,000
1979 1.3 million = 2,050,000
1980 2 million = 4,050,000
1981 3 million = 7,050,000
1982 5.5 million = 12,550,000
10-12 January/February 1983
12 March 1983
14 February 1984
25 1988 (worldwide?)
30 total (worldwide)
Atari's own "Consumer Electronics Division (Jan/Feb) 1983" press kit has a letter about the 2600 (My First) Computer, mentioning "an installed base of more than 10 million VCS owners..."
A January 19th, 1983 Wall Street Journal article has a quote from Activision's Alan Miller mentioning a "market of 12 million VCS units."
A January 1983 press release from Starpath notes there being "12 million Atari VCS owners".
The March 1983 issue of IEEE spectrum states "...over 12 million sold at about $140 apiece".
An article in the Spring 1983 issue of Creative Computing Video & Arcade Games
conservatively estimates 6 million consoles (pg.
Both the April and May 1983 issues of Antic mention there being a user base of 10 million VCS systems, but they would have been using whatever figures Atari was publishing.
The May/June 1983 issue of Atari Inside notes "...an installed base of more than 12 million VCS owners."
A May 1983 press release from Unitronics regarding its Interface Module I refers to "an installed base of more than 12 million VCS owners".
The "Atari 2nd Half 1983" press kit has a flyer about the Graduate that states there are over 12 million VCS owners.
From Jed Margolin's archive of Atari VAX messages is this February 1st, 1984 email from Chris Downend:
|The Quality of 2600 carts is the pits - no doubt about it. The system was introduced in 1977 so it is SEVEN years old. I think Breakout and Space Invaders are decent renditions of the coin-op originals and those are 1976 and 1979 games respectively. But with 14 million 2600's out there, financial issues outweigh aesthetic issues.|
The October 1987 issue of TGM has an article with Atari claiming, "Over 20 million (VCS) units are already in people's homes, and millions more continue to be sold each year."
2 internal Atari memos from 1988 (one regarding Axlon games, and the other regarding Atari hardware) state 25 million systems were sold by then.
The book, Encyclopedia of Game Machines, lists 30 million VCS systems sold (total - worldwide).
The accuracy of these last 2 figures is questionable, unless the figures Atari stated in 1983 were based on domestic (U.S.) sales only. But if true, what reason would they have to do that?
Sales numbers have been reported anywhere from 9-12 million units sold in the U.S. by the time the 2600 JR was released in 1986. Given Atari's own statements in 1983, and the fact that the system was actively pushed by Atari until mid-1984, I'd say the 12 million would be the low-end estimate. Perhaps 12-15 would be more accurate. But to see basically the same figures between 1984-1991 that were seen between 1977-1984 would be impossible, especially considering Atari's own cartridge sales figures from 1986-1990 paled in comparison.
Q: What are the different VCS/2600 models?
ATARI VIDEO COMPUTER SYSTEM (VCS) - model CX2600
Originally released in October of 1977. There are 6 switches on top of this model (Power, Color/ B&W, Left and Right Difficulty (A and B), Game Select, and Game Reset). All the text on the switch panel is in lower-case. The power and controller jacks are on the back. The pack-in game was Combat, which seems an odd choice to make considering that of the 9 games originally released, that's the only one without any 1-player variations. The system also included 2 joysticks and paddles. The in-house nickname for the system, "Stella", was not derived from a female employee like most Atari hardware projects were, but rather designer Joe Decuir's bicycle. The wood grain case was designed by Douglas Hardy and Fredrick Thompson. The original 1977 models were made in Sunnyvale and are called "heavy sixers" (1st photo) by the gaming community because the plastic casing is thicker and heavier, and the base is slightly more rounded than the standard 6-switch (2nd photo), which were produced between 1978-79 and made in Hong Kong. The photos below show the major differences between the "heavy" and "light" 6-switch models:
The original "heavy sixers" released did not have a channel selector switch (it was preset for channel 3. Customers who had a problem with interference from their local TV station could obtain a replacement preset for channel 4); there's no switch on the board, and typically no hole in the case for it (if there is, it might be marked CHANNEL SELECT A/B):
The last "heavy sixers" released included the channel selector switch and modified case. Also, all 6-switch models have the motherboard board within a heavy-duty aluminum casing. You can see this around the cartridge port.
ATARI VIDEO COMPUTER SYSTEM (VCS) - model CX2600A
The VCS was redesigned in 1980. This model, 2600A, has 4 switches on top (Power, Color/ B&W, Game Select, and Game Reset). All the text on the switch panel is in upper-case. The 2 internal circuit boards were integrated into one, and the heavy aluminum shielding was replaced with a thin, metal casing. The difficulty switches are on the upper-backside of the console, along with the power connector, controller jacks, and channel switch; the top edge of the case has raised lettering for each. These 2 photos show the differences with the back of the case between the 2600 model and the 2600A model:
The channel selector switch was also relocated to the back of the case, next to the right controller jack, and is now marked CHANNEL 2-3.
The box shows a few different game-related pictures, but the system shown on the box is a "heavy-four" (which was never produced)! Some cases (esp. those made by Dimerco Electronics in Taiwan) don't have a hole in the bottom for color pot adjustments.
Some of the early 2600A models have "light" 6-switch bottom cases, probably done to use up the remaining inventory. These have a thick, black piece of tape covering the opening for what would have been used for the power and controller jacks:
ATARI VIDEO COMPUTER SYSTEM (2600) - model CX2600
In 1982 the system became known as the "2600", and besides having a black front panel (instead of wood grain) and unpainted trim around the switch panel, the system box was silver. Collectors sometimes refer to this version as the 2600 "Vader" because of the all-black style. The trim around the joysticks was also unpainted. The difficulty switches are marked the same as the later 2600A variant. The manual lists the model number as "2600" (no 'A'). A few systems have the model number "CX-2600 CR". Starting in 1983, both Pac-Man and Combat were included, but paddles were not. A company flyer from that year notes it was priced to sell at under $100. PAL systems have the model number "2600 AP". Some cases (esp. those made by Dimerco Electronics in Taiwan) don't have a hole in the bottom for color pot adjustments.
A slight variation was made with this raised lettering - the original 2600A version labels the difficulty switches as:
A later variation labels them as:
ATARI 2600 (JR) - model CX2100
This is a VCS/2600 in a very compact and sleek case (commonly referred to as a 2600 "Junior"), which was originally designed for other uses (the 2200 and Voice Controller). Mark Biassotti designed the case, based on a concept by Regan Cheng. The system was originally designed to incorporate a new 3-in-1 chip called "JAN" which combined the MPU, TIA, and RIOT chipset. A prototype came with 1 joystick and Combat, in a 'lunchbox'-style box; the released version had a similar box but no pack-in game. Codenamed "Bonnie", development was completed in 1983 and it started shipping the following year. Labeled as the "Atari Video Computer System, Model #2600", it included the Pro-Line CX24 joysticks (same that were released with the 7800). Production stopped in 1984 and when it started up again in 1986, it was renamed the "2600 JR" (some have "JR" on the bottom sticker). At least 3 different versions of this model were produced. The 1st has a short "rainbow" graphic on the top metal panel:
The 2nd has a long rainbow graphic that spans the width of the system:
The 3rd doesn't have a metal panel (and may only have been sold in Ireland):
The motherboards are all copyrighted 1983 and most revisions have the name "ACTION" them (same with 7800 pcbs). This may have been another codename. Several different boxes exist as well and different joysticks were included (CX40, CX24, or CX78). A white JR surfaced recently, which may or may not have been a fake.
A unique 1-chip NTSC variant exists which may use the original JAN chip. The pcb is marked "Rev 4" and there's no date or "ACTION" name on it. This variant is sometimes called a "unicorn". There's other differences, such as no color adjustment pot, input buffer (4050) chip, or stereo output (mono only, as with all PAL 2600 JR systems). There's also a spot for a 24-pin chip, which suggests the pcb was designed to incorporate a built-in game (much like how the original VCS was). The case is exactly the same as the long rainbow version, but with a serial number that starts with "A1" instead of "AT". There's only shielding around the RF module and the pcb ground foil is solid metal (left photo) instead of the typical crosshatch metal (right photo) - both of which can be seen through the bottom case vents:
A white prototype version also exists:
SEARS TELE-GAMES VIDEO ARCADE - model 637.99743
Sears Tele-Games models (called the Video Arcade) of both the 4 and 6-switch Atari VCS versions were also produced. The difficulty switches are relabeled as skill switches, and instead of A and B, they're marked Expert and Novice. The pack-in game was Target Fun (AKA Air-Sea Battle). The full name as listed on the original system box (which shows a "heavy" 6-switch system) was "Sears Cartridge Tele-Games System Video Arcade" on the top, and "Sears Tele-Games Electronic Games Video Arcade" on the side. A later version of the box (which shows a standard 6-switch system) simply had "Sears Tele-Games Video Arcade", which is the name shown on the system itself. The boxes for the games and accessories were black (except for Superman, which was blue) and had the name "Sears Tele-Games Video Arcade". Green cartridge connectors were originally used but were soon phased out or replaced due to high failure rates:
SEARS TELE-GAMES VIDEO ARCADE II - model 637.75000
This system, model 637.75000, uses a special combination joystick/paddle controller (similar to the CX2700s). There are 4 controller jacks below the front edge, along with a power switch. On top are 8 buttons, each with its own LED. On the bottom are the channel (A/B) and TV Type switches. The pack-in game was Space Invaders. It also uses a power supply with a different connector, so standard VCS/2600 power supplies aren't compatible. The same case style, designed by Barney Huang, was later used for the 7800.
ATARI 2400 - model CX2400?
This is the Canadian version of the 2600A "Vader" (4-switch). The box states "Distributed in Canada by Irwin Electronics".
ATARI 2800 - model CX2800
The Japanese counterpart to the Atari 2600. Same as the Sears Tele-Games Video Arcade II. The pack-in game was Space Invaders.
ATARI 7800 ProSystem - model CX7800
Initially released in May 1984 (article) and officially debuted it at the 1984 Summer CES (article), but then mothballed for 2 years before being re-released in 1986. This system uses the same-size cartridges as the VCS/2600 and has built-in software support for all but a handful of cartridges (See "Which VCS/2600 carts do not work on the 7800?" in the Software section of this FAQ for the latest compatibility listing). The motherboard actually contains all the VCS/2600 circuitry and automatically switches between VCS/2600 and 7800 carts.
ATARI VIDEO COMPUTER SYSTEM (VCS) "Promotional model" - model CX2600
This was special promotional version that was produced (in Sunnyvale) in limited numbers, in both 6-switch and 4-switch versions - the only differences are the switches are chrome (instead of brushed aluminum), the orange outline around the switches is yellow, and the box has "PROMOTIONAL USE ONLY NOT FOR RESALE" marked on it.
Some systems (only 4-switch model?) have "NOT FOR RESALE FOR PROMOTIONAL USE ONLY" burned into the bottom of the case:
KEE GAMES PROGRAMMABLE GAME SYSTEM (PGS) - model CX2600
The photo below shows the only Kee Games VCS system known to exist (at least one fake was produced years later and shown at the MidWest Gaming Classic as though it was the original). Kee Games was a way for Atari to circumvent arcade game distributors who demanded exclusivity deals with their competitors. The games Kee Games released were mostly original, but a few were clones of Atari games. The ruse started in 1973, but by the following year most people were aware of Atari's strategy. Starting in 1975, Atari openly admitted the connection in their literature, and by 1978 the 2 companies "merged". The same problem with distributors didn't exist with the home market, and Atari already had a clone with the Sears Tele-Games model, so the reason for why Atari would have produced a Kee Games VCS model is still unknown.
Q: Where were Atari's systems made?
A: The first year (1977), all production was done at Sunnyvale, CA. The following 2 years (1978-79) saw production shifted to Atari's Hong Kong facility, Atari-Wong Ltd. (Atari owned 51 percent of Wong Electronics, according to this article). When the 2600A model was introduced (in 1980), the bulk of production was being done in Taiwan through at least 5 different companies :
Kingtek Electronics Co., Ltd.
Taiwan Manufacturing Corp.
Taiwan William Computer Manufacturing Corp.
TRW Electronic Components Company
Sunnyvale production of the VCS stopped in 1980 (according to former Atari technician Jerry Jessop, some 2600A models were produced there). By early 1983, the bulk of all production of home video games and computers was shifted to Hong Kong and Taiwan (article). An article in the V1N6 (March/April 1983) issue of Atari Age (pg. 2) mentions VCSs, 5200s, and the 400/800/1200XL computers were being made in Hong Kong, Puerto Rico, Ireland, and Sunnyvale, CA., but the article describes 5200 systems being assembled in Sunnyvale.
Q: What VCS/2600 clones exist?
A: The following are those currently known:
Q: What VCS/2600 adapters exist for other systems?
Atari 5200 VCS Cartridge Adaptor - CX55
This device allows you to play your VCS/2600 games on the 5200 using any standard compatible 9-pin D-sub connector. The elimination of the TV Type switch makes it incompatible with several VCS games that use it as part of the game, which is ironic since Coleco and Mattel included it with theirs. An interesting side-note: The VCS Adaptor is actually an entire Atari VCS/2600 system, much like adaptors for other systems. The cartridge port of the Atari 5200 has the necessary outputs and inputs to power the adaptor, and pass the audio/video signals on to the TV. The original 4-port 5200 consoles have to be modified in order for this to work on it. The fact it took nearly a year for Atari to release it after the 5200 was released - when it was mentioned in the original press releases for the system - is yet another example of just how ineffectual Kassar's leadership was.
Cardco VIC-20 Cardapter
The September 1983 issue of Electronic Games (pg. 41) shows an advertisement for Cardapter, a VCS/2600 cart adapter for the VIC-20. The October 1983 issue of Electronic Fun (pg. 26) lists a price ($89.95) and the distributor's address - 313 Mathewson, Wichita, KS 67214. The distributor was Cardco, Inc. in the US, LSI Distributors Ltd in West Canada, Hobby Craft Canada in East Canada, and Audiogenic in Europe. The device was shown at the 1983 Winter CES (Creative Computing, April 1983, pg. 43). Emulation quality and reliability are unknown. The article states the device was shown with much secrecy in an out-of-the-way hotel room with a rent-a-guard at the door. It was housed (temporarily) in an orange cardboard and Scotch tape box, and plugged into the VIC-20's expansion connector. There was a slot for VCS carts to plug into, and a pass-through connection for the expansion connector. The VIC-20's function keys take the place of the VCS switches and the whole thing "worked like a charm". Retail price was $89.95.
Coleco ColecoVision Expansion Module #1
Made by Coleco, copyright 1982. Priced at $60 and available late 1982/early 1983 (listed in the January 1983 issue of Electronic Fun, page 12). This was the first VCS adaptor made for any system (and nearly a year before Atari's 5200 adaptor), and instantly gave the Colecovision the largest software library available for any system. It includes all the console switches an Atari system has. Black, 5" x 10", 1 3/4" high in front, sloping to 2 3/4" in back. Coleco later offered a cartridge adapter to owners having issues with some 3rd-party cartridges not fitting properly. Chips inside are: "COLECO 73192 E4002" (TIA clone?), SY6507, SY6532. Curiously, there is an empty space for a 14 pin chip and assorted resistors and capacitors on the right side of the circuit board. The space for a "Y1" indicates that this was probably intended to be a clock generator - could this board also have been intended for standalone use, such as in a VCS/2600 clone? There is also an adjustment hole on the bottom that turns a potentiometer (probably for color). The Reset button on the main ColecoVision console acts as a hard reset for the expansion module. Sample wording:
Model No. 2405
Coleco Industries, Inc., Amsterdam, NY 12010
Serial # A0065820 For service help call:
F.C.C. ID# BNV8432405 1+800+842-1225
Coleco Industries, Inc. (Nationwide)
Made in U.S.A. Printed in U.S.A. 74859A
A day after Atari's infamous "Pearl Harbor day" announcement on Wall Street, they sued Coleco over the Expansion module. Here's an article from the April 1983 issue of Electronic Games (pg. 10), and a follow-up article from the September 1983 issue (pg. 16). From Michael Current's excellent website:
|December 8th, 1982 - Atari announced that it had filed suit in U.S. District Court, Northern District of Illinois, Eastern Division against Coleco Industries, charging patent infringement and unfair competition under State and Federal law. Atari's lawsuit sought a preliminary and permanent injunction against the manufacture and sale of Coleco's Expansion Module No. 1 which was intended to allow Atari's VCS compatible cartridges to be played on the Colecovision home video
game unit. Atari claimed that the Coleco cartridge adapter infringed two basic video game patents held by Atari--U.S. Patent No. 4,112,422 covering motion objects commonly referred to as players, missiles or sprites and U.S. Patent No. 4,314,236 relating to digital generation of sound and noise especially suitable to video games. Coleco said it would file a counterclaim charging violations of antitrust law by Atari.
March 11th, 1983 - Atari Inc. and Coleco Industries announced they had settled their December 1982 lawsuits against each other. Under their settlement, the companies said Coleco could continue making and selling its ColecoVision Expansion Module No. 1 and also could ship its planned Atari 2600-compatible Gemini Video Game System. However, Coleco would do so as a licensee of Atari's patents, and would pay a royalty to Atari.
Mattel Intellivision System Changer
Made by Mattel, copyright 1983, and developed under the code name "Portofino". Mattel decided to one-up Coleco and release its own VCS adaptor for their Intellivision, thereby instantly giving it the largest software library available. It includes all the console switches an Atari system has. White, roughly about 5-6" square and 2" high, with a piece sticking out of the left side that fits into the Intellivision cartridge slot. Front face had two standard joystick ports. Known to work with virtually all VCS/2600 carts except those that don't work with other adapters. Sample wording:
|(one white label and one orange label) "Model No. 4610 FCC ID: BSU9RD4610
Serial No. 003255
The Changer does not work with the "original" (2609) Intellivision Master Component without factory modification
(see this website for more info).
Contrary to statements on the Intellivision Lives website, the Atari VCS is not comprised solely of "off the shelf" hardware. While they boast that Atari never sued Mattel over the System Changer, Mattel knew full well how more difficult it would have been for Atari to prove Mattel was copying the TIA by using COB technology.
Protecto VIC-20 Game Loader
Rumored to exist. Was advertised by Protecto in mail order ads in during the 1983 time frame. Plugged into VIC expansion connector and provided VCS/2600 software emulation. The October 1983 issue of Electronic Fun (pg. 26) mentions the price and address. Emulation quality and reliability are unknown.
Retrode PC USB adapter
This adapter allows for the insertion of Atari 2600 cartridges in the Retrode’s SNES slot. See Retrode's website for more information.
Q: What VCS/2600 hardware was announced, but never released?
A: The short answer is quite a bit. Here are some examples:
The Graduate was designed by Peripheral Visions Inc. The company was founded in late 1982 and was comprised of 5 former Commodore VIC-20/C-64 engineers: Charles Winterble, Al Charpentier, Bob Yannes, David Ziembicki, and Bruce Crockett. Their idea was for a low-cost computer, called "My First Computer". Designed with a $29.95 price, it was to feature a membrane computer and have BASIC built-in. Winterble presented the idea of a VCS computer to Ray Kassar, who agreed to purchase it for 1 million dollars. This was to be Atari's entry into the emerging 2600 keyboard market, and Atari was to develop the software for it. The unit plugged into the VCS cart port and was self-contained, much like how the 5200 VCS Cartridge Adaptor works (using the base system for power and display only). The designers invented a 3-cycle "Bus Stuff" mode, to achieve a faster TIA register update rate. This works by loading Y with $FF at the beginning of the kernel, and then having the 6507 execute 3-cycle STY $REG instructions. At the critical moment when the $FF is being written, The Graduate hardware steps in and overdrives the desired value on the bus. The product was given the model number CX-3000, and was known by several names during its development ("My First Computer", "2600 Computer", "The Graduate"), undergoing several changes (case designs, features, price points, etc). It was shown at the Summer 1983 CES show, along with the printer and wafer drive, before ultimately being cancelled by James Morgan when he took over as the new CEO of Atari in September 1983. An ongoing lawsuit against PVI by Commodore was likely the main motivating reason for its cancellation. Soon after PVI was formed, Jack Tramiel heard PVI approached Atari and filed an "exploratory" (and ultimately frivolous) lawsuit against them, claiming they stole trade secrets. PVI were forced to disclose details of their VCS project, which proved it wasn't something worked on at Commodore (some of their own management made depositions stating that). Yet, Tramiel insisted that was his product, and pursued the case, even claiming infringement at one point because The Graduate used a 6502! PVI eventually won, but it cost them several years and approximately $300,000 (From "On The Edge: The Spectacular Rise And Fall Of Commodore", pg. 274-279 - LINK).
Q: How do I hook up my Atari to a TV? Or, I've hooked up my system, but the picture is fuzzy.
A: The system originally used a manual RF switch box with 2 screws for the antenna (or cable) and a short, flat cable with 2 "fork" terminal leads coming off it for the TV:
The short, flat cable typically went to the (300 ohm) VHF screw terminals on the back of a TV. Since manufacturers stopped including the screw terminals with the rise of cable service providers and replaced them with a (75 ohm) coax connector, you'll need a small adapter (as shown in above photo). Likewise, the antenna screw terminals on the switch box will need an adapter called an impedance matching transformer (as shown in above photo) for attaching your current TV cable. Some switchbox variations have connections for both antenna and cable:
A picture that's snowy or lacking color usually indicates a connection problem. The system's RF cable may need to be replaced, or the problem could be with the switch box. Old switch boxes may have worn or dirty contacts insides. You can still buy new switch boxes from any store specializing in electronic parts, such as Radio Shack. Make sure you get a manual type; most (all?) systems starting with the NES use automatic RF switches. This type will not work for the VCS/2600 (or 7800), as the signal is not strong enough to trigger the switch completely. A manual RF switch, available at any Radio Shack or equivalent is needed.
A better alternative (picture quality-wise) to using a switch box is to eliminate it and connect the system directly by using a male coax- to- female RCA phono connector:
This will allow you to connect the system to any cable-ready TV.
Remember that having your TV set to the proper channel is necessary, no matter what method you use to connect the system. All but the original VCS/2600 "heavy sixer" models have a TV channel switch either on the back or bottom of the system. The switch sets the output signal to match either channel 2 or 3 on your TV.
If using a wide-screen TV, the ratio perspective will be different (16x9, instead of 4x3), so those used to playing with the original 4x3 perspective will find it a different experience. Flat-screen users (especially with LCD TVs) may experience display lag issues. HD TV users may experience upscaling issues (due to the system's inherent low-resolution). For optimal playing experience, it's best to use a CRT (tube) TV, preferably in standard 4x3 format.
Q: The colors seem wrong. How do I adjust them?
A: To properly adjust your system to the original specifications, you'll need an Atari Diagnostic cartridge. One of the tests on it brings up a color bar screen:
Note the gray reference bar. The purpose of this is to help in adjusting the color potentiometer that's on the motherboard. Most VCS/2600 cases (excluding all 6-switch models) have a small hole on the bottom, which lines up with the pot:
(4-switch model on left; "JR" model in the center; Sears Video Arcade II on the right)
By inserting a small, flathead screwdriver here, you can adjust the colors on the screen until the color bar directly above and below this reference bar are the same. Some of the heavy 6-switch models have an adjustment hole, but the "light" 6-switch models don't, so you have to open the case up. The aluminum casing has a hole on both the top and bottom of it that can be used to adjust the color. 4-switch models made by Dimerco Electronics in Taiwan don't have an adjustment hole either, and neither do 7800 systems.
Q: Where do I get my VCS/2600 fixed, or how can I fix it?
A: In general, it is usually more cost effective to buy another console. Ask online or at your local video game store; they may not offer to repair them, but they may put you in contact with someone who does.
If you're knowledgeable with repairing electronics, you'll want to see this 10-part how-to repair video for VCS/2600 systems. The May 1982 issue of Electronic Games also has this article by Henry Cohen on fixing systems that exhibit loss of color or snowy video. Best Electronics sells replacement parts for all the different Atari models.
Q: How many different controllers were made for use with the VCS/2600?
A: There were well over 100 different types of controllers, ranging from joysticks, paddles, keypads, and trackballs. There's also several 'specialized' controllers, such as light guns, foot controllers, and all-button controllers. Atari Compendium has a comprehensive list of nearly every one.
Q: How do I fix my joysticks and paddles?
A: Best Electronics sells replacement parts for Atari-made controllers. Some parts, such as replacement controller cables, may work with 3rd-party controllers.
Replacement springs for the standard Atari joystick fire button can be made by using a spring from a ballpoint pen and cutting it approximately in half.
Dirty paddles are a cause of great frustration. To clean them, buy a can of Electronics Cleaner/Degreaser (available at Radio Shack, catalog #: 64-4345) or any type of TV tuner or metal contact cleaner, open up the paddles and spray directly into the pot area. Close them up, give them a few twists and they should be good as new. Do NOT use any type of oil or silicon spray (such as WD40) as this will gum up the contacts. If you find using cleaner only provides a temporary solution, the pot may be too dirty and the canister will have to be opened and the contacts wiped down.
Q: Do Bally Astrocade, MSX, or Texas Instruments joysticks work on the VCS/2600?
A: No to all of them. With the Bally Astrocade and MSX, even though they use the standard 9-pin connector, the pinouts are different. However, using the pinouts found in these Bally Astrocade and MSX FAQs, they can be rewired to work on the VCS/2600. Texas Instruments joysticks can be rewired as well, but it would require either replacing the controller wire (TI joysticks are wired in pairs, like Atari's paddles), or making an adapter. A schematic by Gary Cook for making an adapter to use Atari controllers with TI computers appeared in the September 1983 issue of Creative Computing (pg. 140). This could be altered to make an adapter for TI controllers. According to a news blurb in the November 1983 issue of Electronic Fun (pg. 17), Suncom made such an adapter, called TIA, which retailed for $12.95.
Q: How do I use an Atari joystick on a PC/Mac?
A: Here are links to some adapters for the PC:
See the Features section of this site for an article on how to make your own USB controllers.
Q: What hardware peripherals exist for the VCS/2600?
A: Here's some that were released:
Made by Splice. A Brazilian Supercharger knock-off.
Made by Sosecal. Brazilian version of Spectravideo's CompuMate keyboard.
Made by Spectravideo. This is a 42-key touch pad-style computer add-on that adds 16K ROM, 2K RAM, a 2-channel + 2 octave music composer, BASIC, and Magic Easel. The unit looks like a small keyboard connected to a cartridge, which has 2 cables that connect to the controller ports. It has 3 function/display modes: Text (which runs BASIC), Graphic (which runs Magic Easel) and Music. Magic Easel allows you to create photos (with up to 10 different colors) and animations (up to 9 frames) using the joystick). Originally sold for $79.99. This was once quite rare to find until a large quantity surfaced in Venezuela in 2010. There's also a German version made by Universum.
Made by Digitel. A Brazilian Supercharger knock-off.
Made by VGS. A Brazilian Supercharger knock-off.
GameLine Master Module
Made by CVC. See the GameLine entry in the Software section for more info.
Kid Vid Voice Module
Made by Coleco. This was a cassette recorder and cartridge interface. Additional wire connects recorder to joystick port. Voices and songs tell player what to do on screen. Tape shuts off automatically to wait for player input. 3 tapes per game, only games were Berenstain Bears and Smurfs Save the Day.
Personal Game Programmer
Made by Answer. Similar to the Game Genie. Available directly through Answer Software for a short time (for $200), this peripheral allows you to change the code on existing games to your own liking. It doesn't actually store the changes on the cartridge - all effects are temporary. Brown and gold with white keys, the unit sits on top of the Atari 2600. Two cables: one to the cartridge port and one to the power receptacle, connect it. Only 2 are known to be in existence: Al Backiel got his direct from Answer, who later sold it to John Hardie, and Marco Kerstens got his from William Sommerwerck.
Made by Starpath. This is an add-on device that improves the Atari VCS memory, graphics, and sound capability. The unit itself contains 6K RAM and 2K ROM. ROM is in top 2K and RAM is banked in lower 2K. The additional 6K of screen RAM was a huge improvement over the hardware's 128 bytes. Games were distributed on cassette tape. By plugging the Supercharger into the VCS and connecting its cable (with a standard 1/8" jack on the end) to a standard cassette tape player, games could be "loaded in" to memory. Phaser Patrol was also included. The unit initially retailed for $70, but in January 1983 the price was reduced to $45.
Made by Embracom Electronica. Basically a Brazilian knock-off of the Supercharger.
Made by Starplex Electronics, Inc. This was available in either a 9 or 24-cartridge multicart switcher. By turning a dial you can switch between them. The VCS power supply plugs into the back of it, and a wire from the Game Selex plugs into the power jack on a VCS. A note came with it stating if you see excess static with the device attached, Starplex would provide anti-static filters at no cost.
Made by Marjac. A 10-cartridge multicart switcher. At the press of a button, you can switch between them. This was even advertised in the Atari Age, V2N4 (pg. 22), priced at $49.95!
Pirate version of RGA International's Video Game Brain, except this variant has Cat Trax built-in!
Video Game Brain
Made by RGA International. A 6-cartridge multicart switcher. Made in Hong Kong. Warning - this device can damage your games, your system, or both, due to how it's internally wired. Voltage is constantly running through the address and data lines while the power line is floating, when a cartridge is NOT selected! It's possible to modify the device to operate properly and safely, otherwise don't use one until it's been fixed.
Made by Compro Electronics, Inc. An 8-cartridge multicart switcher, with a smoke brown plexiglass hood and 8 sensor touch buttons on the front panel. The manual claimed to "Reduce the wear on your expensive system and cartridges".
Q: What are the differences between NTSC/PAL/SECAM games?
A: NTSC (National Television Standards Committee), PAL (Phase Alternating Lines) and SECAM (SEquentiel Couleur Avec Memoire) are different worldwide, generally incompatible television standards. Why is this information important? Different carts will exhibit different characteristics based on what kind of TV and console are used. For example, a PAL cart on an NTSC console and TV will roll the screen and exhibit a strange color scheme. An adjustable vertical hold is a must in these situations. Another issue is NTSC versions will be ~10% faster and PAL ~7% slower. This is especially important with any contests that involve players from different countries. Most companies developed games in NTSC and later converted them to PAL. Since programmers were mainly concerned with having a stable image and acceptable colors, no time was spent on adjusting gameplay so that it ran identical to the NTSC version. As a general rule, PAL players have an advantage over NTSC players, making any fair competitions between the two impossible. Atari Compendium maintains an NTSC/PAL/SECAM Scanline List with more detailed information.
Q: What is a TV Boy and where can I get one?
A: The TV Boy is a handheld-sized Atari VCS/2600 (made by SystemA) with 127 built-in games that connects to your TV (it does not have its own screen). While it features a built-in GameBoy-like joypad and external 9-pin ports so one can connect one's favorite controller, it does not, alas, have a cartridge slot. Inside the TV Boy is a jumper marked "NTSC/PAL," so it appears that it will work on either type of TV.
Q: Why do some 6-switch systems have vent holes in the top of the case?
A: The VCS was originally designed to produce sound effects internally via 2 internal speakers (much like Atari's earlier dedicated systems), instead of through a TV (via the RF box). The system’s casing has slits on the top-half and brackets on the bottom-half - these were for the speakers. Arcade games from the mid-70s often used 2 speakers, with each being driven by a separate tone generator - one for each player. Atari's Tank coin-ops used this design. This "dual mono" tradition carried over to the VCS, as the system has 2 independent sound generators. Jim Heller, who was a former Atari engineer, stated a last-minute production change was made to drop the internal speakers, since it was felt the audio would be better through the TV set. Due to this change, the 2 sound output pins (pin 12 is the left channel audio and pin 13 is the right channel audio) on the TIA were simply tied together, resulting in mono sound. This also explains why Combat, Air-Sea Battle, Indy 500, and Street Racer (being 4 of the 9 launch titles) are the only 4 games Atari made that were programmed for stereo sound.
The "stereo" mod (described in the Projects section of this FAQ) sends the outputs of one generator to the left channel and the other to the right. As far as "using" stereo is concerned, the games can be divided into 4 categories, though there is some overlap. The 2 channels can be used in the following ways:
1) Some games only use one generator. All the sound will come from one channel, with nothing from the other.
2) Some games use each channel for a particular purpose. This division may or may not make sense spatially or aesthetically. Combat, for example, will use one channel for the left player's vehicle noises, shots, and explosions, and the other channel for the right player's. These assignments will remain constant regardless of where the vehicles move around on screen, so they may not make much spatial sense in relation to where the players are sitting in relation to the screen. Other games may use one channel for background noise and the other channel for shots and explosions. In that case, a left/right division might not be meaningful, but having one speaker closer than the other might be good. With the homebrew game, Medieval Mayhem, any sounds for left side castles come out the left, and sounds for right side castles come out the right. It's also quite noticeable when the dragon flies across the screen.
3) Some games, such as Toyshop Trouble, allocate sounds to the two channels essentially randomly. This allows sounds to 'overlap' (e.g. if you paint two toys in quick succession, the sound for the second can start while the sound from the first is still playing) but would make things sound weird if the channels weren't mixed together.
4) Very few games output sounds to both channels but vary the amplitudes to create a "stereo" effect. Frogger and Turmoil are 2 games that use both channels to create true, 2-channel music. The homebrew games A-VCS-tec Challenge, Skeleton+, and Synthcart also take advantage of the system's stereo capability. The spear level in A-VCS-tec Challenge is programmed so you can hear if the spear is coming from the left or right side. When reaching the middle of the screen, it switches to the other side. Additionally, the spear sound is getting louder when coming closer to the player. So in stereo you hear the spear fading in and out and flying from left to right or vice-versa. Skeleton+ uses the stereo to help players locate skeletons in the maze.
Q: Some motherboards have a space for another chip. What was this for?
A: The original version of the VCS was designed to have a game built-in (Combat for the Atari version and Air-Sea Battle for the Tele-Games version). All 6-switch motherboards have this. There's a space on the motherboard for the ROM chip:
A 2K or 4K ROM chip could be installed here, however, there’s no circuit to switch between the ROM socket and a cart if a 4K ROM is used.
The "unicorn" 2600 "JR" variant also was designed to have a game built-in as well, and can handle a 2K or 4K ROM automatically if installed:
What game was to be included is unknown.
Q: What are the specs for the VCS/2600?
A: The system has 3 main chips at its heart - the MPU, the TIA, and the RIOT. The MPU is a 6507 (by MOS), which is a low-cost variant of the popular 6502. The TIA is the Television Interface Adapter and is an Atari proprietary chip. It was made by over a half-dozen manufacturers, resulting in dozens of variations (see my TIA chip article). The RIOT is a 6532 RAM, I/O, Timer chip (by Rockwell). Early models contain a 4th chip - a 4050 CMOS hex buffer - that was later removed due to being unnecessary.

Q: How large (memory-wise) do VCS/2600 games get?
A: The range is 2K, 4K, 8K, 16K, 32K (Fatal Run), and 64K (32-in-1 and Mega Boy). Games using 8K or more require a programming technique called bank-switching (patent 4,368,515 and patent 4,432,067). Bank-switching increases the amount of a system's usable memory beyond the amount directly addressable by the processor. The programming technique was known about since 1971, as it was discussed in C. Gordon Bell and Allen Newell's book, Computer Structures: Readings and Examples. In the case of the VCS/2600, the system's inherent cartridge ROM limit is 4K. Larry Wagner and Bob Whitehead's development of Video Chess also led to the use of bank-switching on the VCS. Atari's Asteroids was the first game released to use bank-switching, resulting in an 8K ROM. Unfortunately, even with the huge success of VCS Asteroids, Atari was slow to accept the higher cost of using larger ROMs, and finally agreed to after the backlash it received over VCS Pac-Man. By the following year (1983), all 'A-list' titles used ROMs of at least 8K. Other companies soon learned from Atari's mistake and started using bank-switching by 1983 as well. Activision developed their own method (for Decathlon and Robot Tank), as did Parker Brothers and Tigervision. Most companies simply used Atari's method. More information about the different banks-witching methods can be found on Kevin Horton's website.
A few companies (Activision, Atari, CBS Electronics, CommaVid, Mattel, and U.S. Games) developed special RAM chips or "SuperChips" for certain games.
Activision called theirs the Display Processor Chip, or DPC. It was named after the person who developed it - David Patrick Crane (patent 4,644,495). According to Crane,
|The DPC chip added more graphic capability as well as 3 channel music (plus drum), and made Pitfall II: Lost Caverns possible. Unfortunately, the 2600 business died before any other games could take advantage of that technology.|
Atari called theirs SARA and used them in the following games:
Both Garfield and Zoo Keeper were to use the SARA chip as well. The following homebrew games also use the SARA:
CBS Electronics called theirs RAM Plus, and it added 12K of ROM and 256 bytes of RAM. It was used in Omega Race and Tunnel Runner (Wings was to be the 3rd).
CommaVid developed "Extended RAM" cartridges for Magicard and Video Life that offered 2K of ROM and 1K of RAM. According to a company ad, it "provides eight times the RAM available to a normal 2600 Video Computer System game." It was developed by Dr. John Bronstein, who received patent 4,386,773 for it.
Mattel/M Network called theirs "Super Cartridges" and added up to 16K of ROM and 2K of RAM ("Big Game" was printed on the prototype carts), but BurgerTime was the only game they released that used it (In Search of the Golden Skull was to be another).
U.S. Games had a special "RAM/ROM" chip for their Pink Panther game ( both developed by James Wickstead Design Associates), which added 8K of ROM and 2K of RAM., but the company went under before it was produced. NAP bought the Pink Panther game from them, along with the RAM/ROM chip. According to an interview with NAP's Bob Harris (in the Spring 2001 issue of Classic Gamer Magazine) NAP hired a company to fabricate the RAM/ROM chip , but unfortunately, the new chips failed and the Probe 2000 division was shut down as a result.
See this article for more information about these.
Q: What is the VCS/2600 pinout information?
A: Controller port pinout:
D3 D4 D5 D6 D7 A12 A10 A11 A9 A8 +5V SGND
--1- --2- --3- --4- --5- --6- --7---8- --9- -10- -11- -12-
GND D2 D1 D0 A0 A1 A2 A3 A4 A5 A6 A7
* to inverter and back to 18 for chip select
A standard VCS/2600 cartridge contains the equivalent of a 2716 or 2732/2532 with one notable exception: the chip select line is active high, not low. The high order address line of the 6507 (A12) is used as the chip enable. There was at least one company that used EPROMs with a 74LS04 inverter to compensate for this. Note that numbers indicate left to right numbering.
On cartridges, GND was also connected to SGND. Best to make sure that they are wired together.
Q: What are the AC Adapter power supply specs?
|Plug type||1/8" phone|
|Alternative||All Atari-made models of the VCS?2600 have compatible power supplies|
2800/Sears Video Arcade II
|Plug type||coaxial ??mm/??mm|
|Alternative||Atari 5200, Atari Jaguar, SMS / Genesis, TurboGrafx-16|
|Alternative||None, although a 1/8" phone jack can be added and a VCS/2600 AC Adapter used|
Q: Are there any published VCS/2600 technical articles available?
A: Here’s one from the March 1983 issue of IEEE spectrum, titled: Design Case History: the Atari Video Computer System. It is quite an interesting read, although it contains no code. I also have several others in the archives section.
Q: Are there any emulators for the VCS/2600?
A: Several, although only javatari and Stella are still maintained and updated:
Q: How do I archive or dump cartridges?
A: Several different cartridge copier devices were made:
Atari Game Recorder
The Atari Game Recorder is a device that copies carts to cassette tape and also admits the playing of games from tape. Instructions and schematics are in the following issues of Radio Electronics (it's a three-part article):
Dec 84 Vol 55 no 12 p. 69-72.
Jan 85 Vol 56 no 1 p. 51-58.
Feb 85 Vol 56 no 2 p. 69-72.
The article was written by Guy Vachon and David A. Chan. The construction of the AGR is not for the faint of heart, and the device does not handle bank-switched carts - you're limited to 2K and 4K games only.
Atarimax Maxflash USB Cartridge Programmer
Currently sold by AtariMax, this modern device can be used to dump cartridges for several different systems (coupled with a Dumping Adapter) including Atari VCS/2600, 5200, 7800, Colecovision, and Intellivision.
Made by VGS. A device released in Brazil that allows you to copy cartridges. It looks similar to a Xonox cart shell, with switches and LEDs on one end, and a cartridge port on the other. You plug in the cartridge you want to copy and read it into the device's memory. You then plug in a 'blank' EPROM cartridge and write the device's memory to it.
Made by Unimex. Upon its release in 1984, the Unimex Duplicator cost 200 DM, about as much as the 2600 itself. Like the Yoko, it feeds off of the 2600's power supply. There are 4K, 8K and 12/16K EPROMS available for the Duplicator. Similar in appearance to half of a 6-switch VCS, it has a MASTER and a COPY slot. Copying a game takes about 8 minutes. Small changes in voltage, however, will cause the copying to fail, and not all new EPROMs work. So far, the system has only been found in Germany. There are 2 versions - one that's all black, and the other that has a gold plate on top.
Made by Pete McKevitz. Allows you to copy 2K and 4K carts to either an EPROM, a blank cartridge, or both (at the same time). You can also put two 2K games on a 4K EPROM and flip between them via a toggle switch (using the included blank cartridge). How many were made/sold is unknown, but John Hardie found close to a dozen units, with most of them being complete; he sold one (complete with cart and manual) to Jose "wonder007" Artiles in 2006, and brought another to CGE2K7. A 3rd one is on display at the Digital Press store. Mr. McKevitz contacted me in October 2012 and provided the following information:
I designed and built that programmer around 1981/ Spring 1982. As far as development went, I had a shop back then called Pete's Electronic Service & Supply. We were selling satellite TV equipment, Apple II clones, and a few other things, and I did PC board design on the side. I had a good friend named Paul who worked at a Radio Shack down the street from the shop, and after a little persuading got him into Pete's. We worked on the project together and came up with the E-Pro 2000. We actually hand-built about 100 units. I remember placing a half-page ad in Computer Shopper, when it used to be the size of a large Metropolitan phone book. Sales were not good. Atari went into bankruptcy a few weeks later and we scrapped the project and liquidated the entire stock to a fellow in Texas at around $30.00 bucks a piece. I still have motherboards, mem xfer boards, a few game boards, and assorted parts, such as the 24 pin .100 spacing connectors (these were used on the ATARI VCS/2600 game machine itself. They were just not available in those days, so we had to place an order of around 1000 units to have them made especially for us, and they were not cheap as I recall). What I do not have is a complete boxed unit. I don’t know why, but I never saved a complete unit. The E-Pro 2000 and the directly-programmable game carts were all that we did. We had hopes of doing much more, but when Atari tanked as well as everything else in 1983, we just pulled the plug on all efforts in that direction.
The Game Brain
Made by Super Vision. A backup device that allows you to copy cartridges to cassette tapes, using a standard cassette player. It resembles a Supercharger in appearance. It was only available through mail order and cost $98.95, which included a free T-shirt. Collector Rick Weis is the only person known to have one. An ad appeared in the October 1983 issue of The Logical Gamer newsletter (pg. 2).
Made by Yoko. Sold and distributed by a company called C.S.K., the Yoko came boxed in Styrofoam with paper wrapping. The EPROM cart was sold separately. Each cart can hold two games (4K max). The games are selectable via a small dipswitch on the front of the cart. The copier gets its power from the 2600's power supply. To copy, insert the blank cart in one slot and the original in the other, and hit the red start button. The manual contains a list of games that can be duplicated. Oddly enough, the list has many games that have never been released, such as Fall Guy, Alligator People, Voyage to the Bottom of the Sea, Targ, Kickman, Stomp It, and Butch Cassidy. Believed to have been sold only in The Netherlands.
Harmony Cart + Game Brain
A Harmony cart with a modified Game Brain or old floppy drive cable can be used to dump just about any 2600 game made. See this page for more information.
Made in Taiwan. No other information is available about this.
Made by JS & A. A small unit with 2 cartridge ports that allows you to copy 4k or 8k games in 3 minutes with the push of a button. The copier sold for $119 and blank carts were $15. According to their ad, it was developed by a company in Houston, TX and touted as a perfectly legal device (referring to the copyright act amendment passed in 1980), while at the same time promoting it as a good way to make extra money. J S & A (J.S. & A. Group, Inc., for Joseph Sugarman and Associates) also planned to offer 9 exclusive games with the intention that Prom Blaster owners could sell copies to their friends. It wasn't long before Atari took them to court to stop the sale of them (especially since an Atari cart appeared in their ad). They shut down soon after, and the games never materialized. A copy of the court hearing records detailing Atari's cast against them can be found HERE.
Repro Game Kit/Repro Vision System and Repro Cart
Made by Home Vision. This cart duplicating device is much smaller than the other two European copiers by Yoko and Unimex, and is very similar to Vidco's Video Game Recorder. The kit was packaged in a small cardboard box and contains a copier, a blank copy cart (called a Repro Cart, although the picture on the box shows a Repro Card label), and a game cartridge. The copier is a small, black device with a slot on each end with a red button and LED in the middle. The cartridge you want to copy plugs into one end, and a Repro Cart goes into the other. An internal (9v) battery powers it .According to the box, copying takes about four seconds (while the Yoko and Duplikator take at least 5 minutes). It has only been found in Germany and Belgium. The game Parachute was pre-copied on the Repro Cart. Also included as a separate cartridge is the game Robot Fight, which is a hack of Missile Command.
Video Game Recorder and Copy Cart
Made by Vidco International. Very similar to the Repro Game Kit by Home Vision (a copy of a copier?). The cartridge you want to copy plugs into one end, and a a special blank cartridge called a Copy Cart goes into the other. 3 AA batteries power it (the Repro Cart uses a 9v battery). According to a January 1984 article in Video Games, it took 9 months to develop this copier. Due to memory limitations, not every cartridge can be copied, but the unit is fairly reliable. Dishaster was packaged with the unit, along with 1 Copy Cart. The listed entry applies to the complete set (which is usually referred to as Copy Cart, as that's the only name on the box). Originally listed in 1983 at $59.95, and later advertised for $49.95. A sealed copy sold on eBay in 2010 for $3,500.
Q: How do I transfer ROMs or binary files to a VCS/2600?
A: You need one of the following items:
Cuttle Cart - Made by Chad Schell / Shell's Electronics. He made these for both the Atari VCS/2600 and 7800. The Cuttle Carts are no longer made. Used ones occasionally appear on Ebay, but be prepared to spend more than they were originally sold for.
Modified 7800 system - see Eckhard Stolberg's Atari 7800 Developer's Page
Modified Atari Flashback2 system - see Fred X. Quimby's modified Flashback 2 and "Alex 79" variant
Modified Starpath Supercharger (by Bob Colbert)
Q: How do I make my own cartridge?
A: You'll need some equipment - both soldering and desoldering irons, an EPROM programmer, and an EPROM eraser. Parts needed are EPROMS, pcbs (in most instances, a standard 4K cart pcb will work), and an additional chip, such as a 74LS04 hex inverter, or a GAL or PAL chip. What size EPROM and what type of pcb you'll need depends on the size of the game. 2 and 4K games use either a 2532 or 2732 (plus a 74LS04). 8K games use a 2764 and a GAL/PAL chip (either chip can be used, only the programming is different). Larger games, or ones that require special chips such as the SARA require a special pcb.
Apollo designed at least 3 different 4K boards. These were used in Apollo's Lochjaw and Chase The Chuck Wagon carts. Other companies used them for their games such as Gammation (Gamma Attack), Telesys, and Wizard Video (Halloween and The Texas Chainsaw Massacre). They were also sold through Jameco to the public:
Randy Crihfield of Hozer Video Games was the first person to describe how to modify an Atari 4K pcb to make your own cartridges. He later designed and sold new 4K boards.He also wrote a very informative article regarding all the various bank-switching methods, explaining how Atariage's boards work and how to write GAL files for them, where folks can get the software to program their own .jdec files, etc.
Chris Wilkson was the first person to use a PAL chip and design a board for 8K and 16K games. Unfortunately, others in the homebrew community have since taken credit for Wilkson's work, and even went so far as to encrypt their PAL or GAL chips to try and prevent others from copying them. Wilkson was also the first person to design a 32K board.
Robert Demming has a website describing how to build your own 512-in-1 multicart.
Q: How do I add a pause switch?
A: The October 1983 issue of Videogaming Illustrated featured an article by Bob Guerra on how to install your own pause button on your Atari VCS/2600. Actually, it wasn't a true pause button, but rather how to add an extra button to your joystick that's wired up to the TV Type switch on the system.
Victor Trucco has created a true pause circuit that can be added to any VCS/2600 system, similar to how the pause switch works on the Brazilian Atari VCS/2600-compatible system, the Onyx Jr., by Microdigital. Michael Pagano / Vintage Gaming and More sells copies of this.
Q: How do I convert an Atari joystick for use with a PC?
A: Greg Bendokus wrote an article about how to hack a serial-style PC gamepad controller for use with an arcade-style controller. Scott Stilphen wrote a similar article using Gravis USB gamepad inside of an Atari joystick. Victor Trucco has an article on how to make your own USB interface board for use with an Atari joystick. RetroZone also sells a kit called the Atari RetroKit to convert your joystick to USB
Q: How can I convert a mouse into a paddle controller?
A: Eduardo has done this, you can see some pictures and general instructions here.
Q: How do I convert an NES controller to an Atari pinout?
A: See the following video.
Q: How do I convert a Sega Master System light gun to an Atari pinout?
A: The Aug 1988 (Vol 7, Num 4) of Antic contained an article called First look: Inside the XE Game System: Hardware surprises revealed. It described the conversion:
To modify the Sega gun for the Atari, you'll have to cut off the incompatible connector. The wires must be stripped back and soldered into an Atari joystick connector as follows:
|SEGA GUN||ATARI JOYSTICK PORT|
|Blue wire||Pin 1 stick FWD|
|Gray wire||Pin 6 trigger|
|Green wire||Pin 7 +5 volts|
|Black wire||Pin 8 Ground|
Because of the close-fitting connections with the XEGS ports, don't wire in a DB9 female connector that has "ears". Most joysticks don't have wires for unused signals, so cutting up an old joystick cable may not work. Specifically, an Atari joystick does not need the +5 volts, so there isn't likely to be a wire connected to pin 7. However, you can find joystick extension cables at Radio Shack, which have all nine pins wired from male to female.
Once it's all hooked up, you'll notice the gun fires when you release the trigger; the Sega trigger wiring is the opposite of what the Atari light gun uses. To rewire the trigger switch, remove the 5 screws (one is under the Sega logo on the side), find the trigger micro-switch with three connections, and wire it to the normally-closed contacts.
A schematic can also be found on John Soper's website.
Q: How do I make a glove controller, similar to Mattel's Power Glove for the Nintendo NES?
A: Eduardo has done this, and you can see some pictures and general instructions here.
Q: What audio mods are available?
A: Modifying an Atari VCS/2600 for stereo sound is a simple project that involves adding a couple RCA phono jacks to the system case, and wiring them to the output pins of the TIA chip. Victor Trucco wrote an article on his method.
Some of the more professional video mods (below) also include support for stereo sound.
Q: What video mods are available?
Nathan Strum has a nice comparison site of some of the various A/V mods.
In my experience, the 6-switch models offer a superior picture output, compared to the 4-switch and JR models. Coupled with a coax-to-phono connector, they offer a picture quality that's comparable to any mod, and you can obtain composite A/V output if used in conjunction with a VCR.
easterQ: What console mods/updates are available?
A: For 6-switch models, a mod can be done to fix incompatibility problems with certain cartridges (such as River Raid II).
For 4-switch models, there's an Atari tech tip (#4) regarding adding an 820 ohm, 1/4 watt resistor between pins 6 and 9 of the TIA chip (A201) on all Revs (up to 15) to improve color saturation. See the 2600/2600A Field Service Manual in the documents section of Atari Compendium's archives.
Q: How do I build my own rapid-fire module?
A: The Spring 1984 issue of Special Projects featured an article by Jim Stephens called "Build Fire-Fli" on how to build a rapid-fire module for your Atari VCS/2600.
John Soper posted this autofire circuit by Marco Antonio and Checa Funcke.
Q: How do I program my own VCS/2600 games?
A: Back in the 1970s, a major financial investment in specialized equipment (such as a Genrad) was needed, but now programming a VCS game can be done with a standard PC and a few software tools. You need a fundamental understanding of assembly language programming, as well as basic knowledge of the Atari VCS's 6507 processor chip (which is a variant of the more-popular 6502). Even the most novice programmer can use a program like Batari Basic to program games for it. The main online source of information for VCS programmers is the Atariage website. A good place to start is with Andrew Davie's 2600 Programming for Newbies; a copy of it, along with other articles, can be found HERE. Prior to that, the Stella mailing list (also know as the Atari 2600 Programming list) was the go-to place, but since April 2006 it's no longer supported (here are the Stella list archives which still contain a lot of valuable information).
