TRS-80

My first computer was a TRS-80 model 1.

I had so much fun with it that it gave me the motivation to complete a degree in computer science.

And why not write an emulator of the thing.

Clicking on the picture below – or Here – will bring you to my trs-80 emulator.

    Dear Ve2Cuy,

    I really like your TRS-80 emulator. Could you please convert your Macromedia Flash TRS-80 emulator into a standalone *.EXE file so I can run it from folder under MS Windows 7?
