I have bought this mpu004 board for my data east star trek 25th anniversary pinball and have followed the instructions that have came along with it for my pinball and removed the two chips from my old board to the new as it had said in the instructions i have left the jumper wire where it was rather then moving it for my old board had it at the same place i have put the new board in where the old one was and the new board had booted up and in full operation as the old one did and now it works as it did before and like nothing had happened the pinball works very well and as it should i am very happy again to see this pinball again play as it should with no problems
New life for old machines not ready to give up - I’ve tried to repair old mother boards only to have some else go wrong take my advice - replace it with this
