Original, Atari Space Duel arcade game circuit board from 1982. This board was tested a few months ago and passes the rom and ram test on boot-up but doesn't do much else as we recall. Board was tested with new AVG chip, which we have since pulled (the original was bad). Board appears to be missing a caps, but otherwise complete and in good condition, no physical damage or corrosion. We just have too many broken boards to deal with these days, so this one is sold as-is.
See pictures for more details, sold as-is needing some repair work.
