Q*BERT

• Several early units were shipped with "@!#?@!" on the marquee instead of "Q*bert".

• A harder version was programmed, titled Faster Harder More Challenging Q*bert, but it never went into production and no dedicated cabinets are known to exist.

• A special Mello Yellow version exists (picture #1), along with a 7-11 version (pictures #2 and #3).

• The game suffers from a high sound chip failure rate probably because the LM379 audio amp is rated at 28 VDC and the power supply pumps 30 VDC through it. Replace the 30 volt Zener diode on the regulator board with a 27 volt Zener, equal to or greater in wattage. This should help prolong the life of the audio amp.

• RUMOR: Some players state that the reserve lives counter rolls over at 255 (back to 0); others say 256.  Does anyone know for sure?

• RUMOR: There's a trick that causes no enemies to appear. It involves remaining in the lower-left corner.
