Bally Star Trek Circuit Board Repairs
I've been repairing a few classic Bally games lately, so it's only fitting that this one came into my care recently. Star Trek (Bally, 1979) has some cool playfield features including a saucer which spits the ball out into the pop bumpers, and a free ball return lane. Star Trek appears to be the only Bally solid state game that had a free ball return lane feature, and it was a great way to rack up scores by collecting bonuses continuously. The "Where No Man Has Gone" horseshoe at the top left of the playfield was also a cool gimmick, causing the left pop bumper to fire the ball back at the left flipper.
This will be a relatively short blog post as this restoration was focused mainly on circuit board repairs and upgrades. Only minor playfield repairs were conducted, and the machine was otherwise in good, playing condition. The playfield was stripped and cleaned, various broken parts were replaced, and the flipper assemblies were also rebuilt. However, there's nothing particularly exciting about any of that. Instead, I intend for this blog post to serve as a generic reference for those troubleshooting classic Bally boardsets and to explain some of the basic modifications and upgrades I perform.
Trident (Stern Electronics, 1979) was my first foray into classic solid state (SS) game repair for a customer. I had bought Stars (Stern Electronics, 1978) a little while ago and while I hadn't restored it yet, I had done a lot of reading about common problems, the boardset, and playfield mechanisms. While I initially wanted to work on Stars as my first classic SS restoration, a customer approached me about fixing his Trident so I decided to bring this one back to life first. He had actually asked about selling the machine to me, but instead decided that he wanted to have the game repaired so he could play it again. As this wasn't a full game restoration, this blog entry will be shorter and will cover only the more interesting aspects of the repairs.

Running this website is a hobby for me, just like pinball. I like being able to show my restoration work to everyone so that others can learn from it and learn to fix their own machines. If you enjoy reading the content, please consider donating to offset some of the website's operating costs.
