SepTandy 2021: TRS-80 Repair Part Deux

For once I actually delivered, here's part II of my TRS-80 repair saga. And spoiler alert, I actually managed to fix it.

I don't have much to add here other than taking a moment to marvel over the fact that the computer ran at all with such a major issue in the power supply. The plastics of these old machines are starting to turn into dust but those old TTL electronics are nigh indestructible almost fifty years later.

Septandy Video: Repairing an original TRS-80 Model I

In case anyone actually reads this, long time no see.

I took a long hiatus from working on my homebrew video project because of mostly work-related stress. Realistically I'm not sure how much hobby time I'm going to have for a while now, but since it's September, which a subculture of the Internet refers to "SepTandy", I decided to post a Tandy related video or two.

In late August I saw a TRS-80 Model I keyboard in unknown condition for a "reasonable" Buy It Now price (by today's standards) and decided to bite. I already have a Model I, the unit I bought at a garage sale in a huge bundle back around 1990, but it's had a very rough life. Worst case I thought I might get some usable parts for that machine, which at the very least needs a new keyboard, best case I thought I might get a "runner", or at least one that could be made to run, without too much trouble. It turned out the machine I bought mostly runs, so the next few videos on my channel are going to focus on trying to fix it. Here's the first in the series.


Spoiler: If I can get this machine running I think I'm going to try refocusing my DIY video project temporarily back towards the "retro video card" goal instead of going straight to a full computer. If things work out I'll explain why in a future episode.
