How's it coming along? I'm not sure that it would be worth fixing to be honest. There has to be numerous faults with it, and things get much harder to troubleshoot once there are a number of problems with the unit. But a good cleaning is a good start.
Agreed, I think I’m going to clean the case and make it a sort of display item. Remove the motherboard and maybe display that alongside. Hoped I could use one of my MZ80K’s to test the board but they couldn’t be further from compatible then they appear to be… Thanks for your comment!🙏🏻
