Quoted from jrpinball:Yeah, I was going to say, "Play Mates" and "Domino" would have different motor boards. Could these maybe be replacements for the original sand resistors? Do you have a schematic?
that is what i thought. those game a quite different in game play. pic doesn't look like there were relays removed so sand resistors may have been stock. i never had my head in a playmates so i have no clue
