TRS-80 Model III with 16K RAM, no disk drives.


Specification

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


Condition

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 missing.

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.

Usage hints

Switch to 500 baud:

>POKE 16913,0

Load and start a binary program from cassette:

>SYSTEM

Type the first letter of the file name

*? X

Wait for loading, the run it:

*? /

Load a basic program from cassette:

>CLOAD

Wait for loading, the run:

>RUN

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.
