I’ve run into this problem at least 3-4 times in the last month with different early Bally/Stern solid state games: The game boots and appears to work but you can’t start a game and/or many switches/buttons don’t seem to work? Before you dive deep, try this simple, easy trick.

I’ve been working on a new project that I’m very excited about. There’s been a movement to create an inexpensive, non-destructive and simple way to mod early Bally/Stern solid state games and add more features. In this video, I demonstrate an early prototype of the system used to modify a Bally Mata Hari pinball machine to include new features such as a skill shot, modes and even a wizard mode.

As part of the ongoing restoration of a 1979 Stern “Trident” pinball machine, here’s a series of videos outlining how to replace the rectifier board on these games. This varies a bit between Stern and Bally due to wire color codes. References are here.
Let’s pull a game out of the barn and see what we have? Peer over my shoulder as I take a look for the first time, at a picked up game and see what it needs to be restored. From beginning to end, I will chronicle my progress taking a non-working game and making it play.
This is a common problem that happens with old electro-mechanical pinball machines. One minute it’s playing fine, then the next there’s a loud buzz and/or the scoring runs continuously or doesn’t score properly. What’s the deal with that? I’m going to show you one of the most common causes.
Over the years, probably one of the most asked questions I’ve gotten from people is, “Whatever happened to that Earthshaker you were working on?”
People are referring to this video series: Williams Pinball Earthshaker Looks Like It was in an actual Earthquake!
I picked up this game nine years ago. Pulled it out of a filthy house where the game had sat for years, no legs, no glass, non-operational, in a house full of cats. The game looks like it has numerous things living in it, and the cabinet became a cat scratching post.
The more I looked at it, the more problems I found. The game had been monkeyed with in more ways than I’d seen with any other machine. Nonetheless, I managed to actually, finally get the game to boot up, but it was so horribly mangled in so many ways, it would take years to acquire the necessary parts at reasonable prices, so I stored the game and would pick up parts here and there over the years, hoping one day to restore the game.
Last year a friend inquired about the game and I realized, I didn’t have the time any time soon to tackle this project. I had so much going on I decided to sell it to a friend who I knew would invest the time needed to bring this treasure back. So I gave him all the parts I’d collected, including original cabinet artwork that I got from Gene Cunningham of Illinois Pinball.
The other day, my buddy Josh contacted me to let me know he had finished the restoration and if he could bring the game to the PinChurch to share with others. I jumped at the chance to see what progress had been made with the game, and share with everybody else.
Before I show you the AFTER, take a look at these two BEFORE videos:
You can find more details on the repairs and early restoration here.
Here’s a video of the restored Earthshaker – check it out – amazing work!
Here are some pictures:
Switch stacks are the primary parts of electro-mechanical pinball machines, triggering game activity. I go over in this video, how they work, the different types of switch configurations, and how to clean and maintain them so they work reliably.
