I have 2 Bally EM games. Old Chicago and Capt. Fantastic. They were both produced in 76, with Capt. coming out first. I have a question about the behavior seeing as they are both late model EMs from Bally, but have different behaviors.
Old Chicago will only put 5 maximum credits on the credit unit. You can keep clicking the coin switch, but no more credits will be added. Capt. Fantastic will let you keep adding credits until the wheel is maxed (I think 25 is max).
If you add a credit, during a game, Capt. Fantastic goes to game over, no matter where in the game you were or what player was up. Old Chicago will accept the credit and play on.
Not sure if this is correct or if one of them is not working right or both?
*I know I can rig free play, but I like to drop coins in my games.
