APB CPU Board

Complete, Atari System 2, APB arcade game circuit board from 1987 that does not work.  This one seems to be close, it boots with a 6502 processor not responding test. We have tried swapping the 6502A processor and a few other socketed ICs, but no change, just don't have the time to fix this one so we're selling it as-is.  Boardset is fairly clean and complete, should be repairable, but sold as-is, needing repair.
