OK so get this, I found a new old stock bally/williams fliptronic 1 board from a dealer. I think I hit the jackpot because of how hard they are to find and it was cheap and still in sealed static bag, my AF fliptronics board is working but has seen better days. So I swap the boards that are identical in every way down to part number and rev. number. the board does not work at all! WTF? I have no clue whats wrong, Ive tested the transistors and they are good so IC chips??? help??
