i dont have a camera that works anymore, uum i can give a better description of it but thats it. i did give parts numbers off the back of the board... this board doesnt have a LM3900 chip on it just 3 caps, 1 ceramic resistor and a pot and transistor. no voltage reg here.
 
I have the Space Zap and Gorf manuals sitting in front of me, neither of those.
The P/N for these is A092-90411-A000
You could look through some old manuals to see if you get a hit.
 
i found an old post that says these might be one of the many galaga ps boards that came in galagas, but i would like to know what other games if could of been used on, uum i cant really find no other information other than that, anyone else know.
