Gorgar Pinball Restoration Episode 02

Gorgar Pinball Restoration Episode 02

So, I’ve been working on the power supply board as it has to be fully operation before anything else can even be checked. Its also probably the easiest of the boards to restore as there is little to no logic on the board. I replaced 3 of the 4 main capacitors. The big one (yellow) I could not find a replacement for at my local electronics shop, so I will need to source that from the beloved Internet.

Since I have my Firepower motherboard on my bench, I decided to pull the MPU from Gorgar and just see how it would react on the bench. I cleaned up a bunch of the black suet on the board and hooked it up to the old PC power supply that I use for testing. To my surprise, the MPU appeared to boot straight up. Incredible!

If this holds out, then we could be in for a much easier restore than the Firepower. The MPU and Driver board on that system is in bad shape and is taking forever to repair. I did see that the sound board on Gorgar is pretty suspect. There is a large capacitor on it that looks really bad, I’ll need to order a replacement for that as well.

Anyway, I can’t wait to put some of this back in the machine and see just what happens. Sometimes, all you can do is just plug it in (within reason) and see what works.

Matthew Graphman is a thirty year veteran in the information technology world. He studied writing, drama, as well as computers while attending Bob Jones University in the late 80’s and early 90’s. There he met his wife, Wendy, of twenty-five years and started a family. He currently resides in Bloomington, Indiana with his wife and two children, Kathryn (Kat) and Ethan. His oldest son, Sean, is married and lives on the East Coast. Matthew has long been a fan of fantasy fiction. His first attempt at writing was brought on by his roommates in college. As a result, he wrote his first - still unpublished - fantasy novel. After graduating, Matthew continued his writing exploits, but his focus was mostly around theater. After developing a series of children's skits in the 2000's, he was encouraged to take the skits and convert them into a series of children's chapter books. To date, he has written five of the fifteen stories in the "Chel & Riley Adventures" series. Taking a break from creating children's fiction and drama, Matthew decided to reach back, at the request from his daughter Kat, and create a fantasy world that mixed all of her favorite thematic elements. This series is currently outlined to cover five volumes; however, he is convinced that there could be many more stories that evolve out of this new universe. Matthew is a recent winner of the 2016 and 2017 NaNoWriMo challenge.
