![]() Click here to see a close-up of the WPC board. |
Beginning in 1990, all Williams and Bally pinballs used the same MPU (MAIN PROCESSOR UNIT) board, the WPC (WILLIAMS PINBALL COMPUTER) board. If someone forgot to change the three AA batteries on your board, they've leaked by now and there's no fixing it. The good news is that we stock brand new replacement boards, ready to plug in to the pinball game of your choice. These are BRAND NEW BOARDS sold outright; No trade-in necessary. This new computer board comes to you complete, including the big square ASIC chip in the middle of the board, NV-RAM and a GAME ROM. You just tell us the name of your game when you place your order. We'll install all necessary chips and test the board.
