I have a MPU main board that needs desperate help, it's by Data East Simpsons, and maybe for a Williams Cyclone Pinball game. I know a new board CPU for data east Simpsons is $300. What's the going rate for repair? Anyone know of good reparable companies that are fair? Even if I bought a new board, maybe I will send a board for repair to have a back up. My first board is Data East 520-5003-03 cpu 9009008. The Simpsons game played with no problem but when you turned the game on it said memory issue open door. So I tried changing the battery pack, but to no prevail. Where the front burnt spots are, on the front board those things get very hot. Thanks for any insight. Have a pintastic day.
