Since the wiring is horked, and you apparently have no board, then I just suggest getting the trackball Multigame PCB from arcadeshop. Oops, looks like the discontinued it and rolled it into the programmable Multi-PCB. Either way, that will get you Centipede, Millipede, Crystal Castles, Arkanoid (and apparently, Missle Command and Super Breakout), and it will be more reliable than an original board.
