I have an original test piece of a digital solid state Solar City, that's the earliest Gottlieb that I know of that was made before System 1. This particular game and board set was one of the one's Gottlieb didn't select as their new system when they were looking to go SS on their games. It's very unique and has one of a kind boards in it. Unfortunately, the CPU board has very bad alkaline damage to it and might not be repairable. I have it planned as a back burner project to bring it back to life, I want to hear the sounds from the sound board they made.
