Quoted from Pinball-DOOD:Can anyone recommend any replacement MPUs? I have not been out there to solve the issue yet but Iām thinking it would be a good solution for now.
Msg this guy on ebay. johan6685 Ive bought a few 80b mpu boards from him. All chips have sockets so if your pin eats it you can fix it. Switch matrix on the 80B can be a real bitch. And there was a guy on here selling replacement power supply's. You want 5v no more no less.
