#modeliii

The TRS-80 Model III is fixed, cleaned, assembled, and tested. Nice to have this piece of computing history in the collection. I have memories of using these in high school before the IBM clones took over.

Quiet Friday evening pulling keys and cleaning the Model III keyboard.

After some fiddling with IMD both drives are aligned and the Model III is booting off its drives once again. Time to tackle the dirty keyboard.

Good and Bad news with the Model III. Hooked up a Gotek and the machine boots – so controller is good. But when I try and format or copy to the drives same errors on both. So pretty sure it’s the drives.

IT’S ALIVE! First power on for this TRS-80 Model III and the system is up and the screen is good. Unfortunately no “Diskette?” prompt and no boot from the disk drive. So not sure if it has controller or just drive problems.

Stepper motor on the Model III drives seemed very stiff and sticking. A couple of hours of exercising both drives and they’re working much smoother.

TRS-80 model III is blown apart. All is there and looks good. So time to start cleaning and get it re-assembled for a first power up.

Oh! I don’t like that. Metal washers under the power supply. And only 3 bolts so one of those was just floating there – that’s not good. Time to print up some plastic washers.

Good news is this TRS-80 Model III case is not empty, looks likes all the guts are still there. We have some gooeyness on the anode cap and some RIFA caps just waiting to give the next guy to power this on a bad day.

This TRS-80 Model III has a 16K badge and the model is 26-1062 but we have dual drives and an extra port so some upgrades were done in the past.

For #SepTandy 2025 I’m going to restore this TRS-80 Model III I picked up a while back. I have mixed feelings about these computers. My high school had these and being a Commodore kid they nothing for me at the time.
