rdagger Posted September 13, 2018 Share Posted September 13, 2018 I finally got some time today to take a crack at repairing an Astrocade that belonged to my step dad. I was hoping to get some more historical data on the unit. I think he bought it in the late 70's. It has a sticker on the board with HV-A25782_. Is that the serial number? The PCB silk screen includes the number MM T1 A084-90701-B620 A080-90701-B620 and is labelled MIDWAY MFG. CO. A BALLY COMPANY. The date codes on the IC's are between 1977 and 1978.

rdagger Posted September 19, 2018 Author Share Posted September 19, 2018 I just noticed there's a sticker underneath with the serial number. I'm guessing 4255 is an early model. Quote Link to comment Share on other sites More sharing options...
