I never had one of these machines, but I Googled the
schematics + service manual. The service manual
actually has significant programming information. I
THINK it was a 6802 or 09, and the service manual has
enough memory map info as I recall. IF you are really
stuck I'll fish around for it.
What struck me on the schematic was how ingenious
(that is, cheap and effective) the hardware was; it
used ONE moto 1408 D/A converter and a very
inexpensive (but obviously good enough) sample and
hold. Jeez, the chip wasn't that expensive (like,
maybe $1.00) even in 1980.
Most of the websites say that this was a great product
but didn't sell quite enough to survive the Great
Video Game Crash.
