Bally Playboy 1978 Help

Post by Kevin »

Hi All

I am just getting into the hobby ... trying to get a few machines for my basement. I picked up a 1978 Bally Playboy about a week ago with some issues ... getting them resolved one by one. Maybe someone has some tips that can help me speed up finding / fixing a problem.

Player 2 score display shows credits and match, and the credits and match display show same but a little flakey … I assume that maybe an enable chip is bad?

Thanks, Kevin

When you have problems with those old pins, most of the problem are related to the connectors and pins. Try to put pressure on the connectors on all display and see what happen ! Maybe you will need to reflow pins and/or change, repair connectors.

If wiring and pins between MPU J1 and individual display connectors are confirmed correct,
try replacing U11 on the MPU (or swap U10 & U11 on the MPU).

Turns out the 4 keys at the top are working like they are supposed to (just not how I expected).
After RTFM I discovered that the dip switches can group the top 4 keys in pairs or individually ... so all is well.
I guess I expected flipper presses to roll the lights on the four key lanes ... seem to recall other games working that way.

That's what I was thinking. The dip switch was just set to the LIBERAL setting. With these older pins, you gotta start thinking in more primitive terms. Don't expect to be controlling the top rollovers for a couple more years. :mrgreen:
