    I have a MPU-100 that will randomly jump into test mode while playing, have narrowed it down that it is a MPU problem, swapped in a good mpu and it plays fine, swapped PIA's, no change, just wondering if anyone else has seen this happen, its like the matrix is getting a signal from somewhere. figured I would ask here first , never seen this issue before

    I just replaced the mpu with a bally -35 and its now folded ready to go to the new owner, I'll bet it is a cap, hard to check on the bench, I have a eightball I can try it in once I pull it out
