In the (about) ten years since this thread was last active, I came across a Bally 'Mazooma Bell", which is a close relative of the Gold Cup, and thought it might be helpful to share some pics of the innards. These Bally machines are completely different from the more familiar Keeney and Games flashe...

Does your Bingolette not have a circuit diagram inside? Here, I'll post one for you in German I'm afraid. The six contacts at the end work the payout solenoid, as you should be able to follow from the diagram. The relay that self-sticks is the anti-cheat relay, aka the tilt relay. There's very littl...

Frank - delighted to meet you! I well remember your song. I remember dancing to it at "The Ship" disco in Dymchurch the night I had sex for the first time with the girl who became my wife. That was a good song to be remembered for (and a good thing for me to remember it by). But I never connected th...

Splendid news.

I had an early ACE microprocessor controlled machine - perhaps you'll recognize it. It is the only piece of electronic equipment I've ever come across that used the Intel 4004, the first microprocessor ever made. Unfortunately it never worked properly so I broke it up, keeping only the rather attrac...

When in doubt, it's always safest to ask.

The yellow produces 25V with respect to the orange, and the red produces 25V with respect to the black (common). So when you connect the orange and the red, you get 50V between the yellow and the black, and 25V between the orange/red and the black.

No, it won't. You get 25V between one end and the middle, and 50V between the same one end and the other. Without actually being there and looking at the wiring, I'm not able to give you specific advice, but you can trace it off the old transformer. The 25 and 50 volt circuits will have a common con...

Unfortunately it's illegal to offer those old machines for play in Nevada now. They don't have the new-fangled electronic monitoring - shoot, you can even open them without an automatic alarm being sent to the authorities - so Gaming Control is constantly worrying that they'll be cheated out of a ni...

You could always replace your one transformer with more than one transformer. 6V trannies are easy and cheap, and all it does is run the lights, so a 6V 1A will do you. As for the other, look for a 50V with center tap, or 25-0-25, which you should find at Farnell. One end to the center is 25V, one e...
