Original Williams CPU board, Rev B. used in its Joust, Robotron, Sinistar and Stargate arcade games. This one boots to random ram errors, we tried swapping a few ram, but no real change. We have done no other troubleshooting and just don't have enough time to fix everything we find these days. Board is clean, we noticed the reset switch was broken, but otherwise in good condition and should be repairable.
See pictures for more details, board is sold as-is, needing repair.
