What's the best method for bench testing reflexive solonoids? I have a 2nd revision Data East CPU board, and I want to confirm that the reflexive solonoids work. Sadly, I don't have a game that goes along with the board, only a 3rd revision game or a system 11 williams game. Can I stick the board in a system 11 (assuming I jumper correctly for the Williams ROMs)? I know they work slightly differently, but I don't know them well enough to know what the difference would be.
