MPU board Williams WPC 89, main CPU/MPU board used in Bally/Williams WPC-89 era For Sale

Williams WPC-89 System MPU board (A-12742) — the main CPU/MPU board used in Bally/Williams WPC-89 era games.

If your original board has suffered battery alkaline/acid damage, this is the clean, reliable replacement path to get your game back in play—fast.

ASIC, EPROMs, and the processor are not included and must be transferred from your existing board. ASIC and processor are also available separately — see related items.

To protect the ASIC and the socket during the swap, we strongly recommend using an ASIC chip puller.
