Wasn’t this Marvin’s RCT that was up and running at the Cleveland Show?
I had a RBION once that exhibited similar symptoms. A previous owner repaired some transistors or diodes on the board, can’t remember exactly, and didn’t clip the leads short enough and although the game played fine when I tested it it was crazy after I moved it as those leads were now shorting out on the backplane.
After fixing that I had an issue with U213 I think which is the security chip. It had some battery damage that was very hard to spot but enough to be a problem with boot up.
I have a few extra if you end up needing one.
