I have a eight ball champ that has a weird problem. The machine will add players or start a new game without the replay button pushed. It will sometimes tilt without it being nudjed. I have disconnected the cabinet jack to the driver board and it still does it. All the electrolytic caps on all the boards have been changed. I’ve swapped the 2 PIA chips, still same thing.
Could the next things to be changed are the 6803 mpu chip, ram chip, or driver board eprom?
Thanks for any help.
