TRS-80 MODEL III Micro Computer MATRA-TANDY model no. 262-1062 Serial no. 002076

16K RAM No disk drives Realistic CTR-56 tape recorder


This was the first computer I used. It was bought for my older brother in 1983.


Has original (optional) anti-glare screen.

After some time the left side of the screen image becomes a bit 'folded'.

Has original tape recorder, but the cable is lost. It is not impossible that the original box still exists (need to search for it).

The cassette cable is simple to assemble yourself (jack plugs for mic/ear/motor to DIN), it did only the ear.

I successfully loaded some programs from old tapes, although most gave errors.

Connecting to a PC using PlayCAS, I was able to run some binary games.

While loading, stars appear. A fixed star is always there and a blinking star which means it's loading. You need to tune the volume. A C means the volume is to high, no star blinking star means it's too low.
