This was intended to be a quick project, but it turned into a huge ordeal. A failed power supply meant that several custom chips were irreparably damaged.

Big Blue vs. The Tandy 1000SX

Thanks to the incredible kindness of another Tandy nerd, I’ve gotten a replacement Light Blue chip, but will the Tandy 1000SX finally work properly? Let’s ask the four years that I spent trying to figure out what else was wrong with it.

Foiled again by the Tandy 1000SX

We fixed the 1000SX’s power supply, and tested the motherboard for shorts. There’s nothing left to do but put the computer back together again and see if it works. And take it apart again. And to wish I had a fully-operational chip fab and precision schematics of every custom IC. Yeah, this one is gonna take a little more time.

Tandy 1000SX power supply is back from the dead

When we last encountered the Tandy 1000SX, it decided to bravely blow itself up rather than face us in battle. With a lot of elbow grease and a little bit of solder-slinging, this testament to 80s shopping-mall computing will live again.

Will It Short? A Tandy 1000SX motherboard inspection

Last time on the Tandy 1000SX show, I blew a hole in a power-supply capacitor without even getting the machine to boot. Talk about ungrateful! At least it gives me an excuse to buy more tools.

Tandy 1000SX power supply has an oops

I picked up a Tandy 1000SX recently. My plan is to use it for experimenting with Tandy graphics and sound, and maybe even port a few hobbyist games to the platform. As per usual with my pick-ups, this one needs a little bit of work before it can be usable.
