silvestrons bits and bytes | Tough rescue of a Sega SC-3000 Personal Computer! @silvestronsbitsandbytes | Uploaded May 2022 | Updated October 2024, 7 hours ago.
I bought another dead computer, and had probably my most involved diagnose and fix yet! This Sega SC-3000 Personal Computer has quickly become one of my favourite items in my collection... and not just because of the work involved!

I am NOT an expert, I have genuinely NO idea what I'm doing, and mostly just glue things together and use a lot of Google-fu until stuff works. I've been tinkering with electronics since I was a kid, but have no formal training and will probably do things incorrectly. If you learn something from this, that's awesome, but trust me - I'm learning too!
