Black Widow

The only pcbs that have the Black Widow name in solder trace are prototypes (picture #1).  Every Black Widow pcb sold by Atari was a converted Gravitar pcb and will usually have a sticker over the Gravitar name (picture #2).  Conversions were either done at the factory, or by operators with field kits.  Factory conversions included mods to the audio section that most operators didn't bother doing (the game will still work, but the sounds won't be exactly correct).
