I don’t remember if I used Model II or Model III Trash-80s in computer class in high school. I did have a floppy full of stuff I programmed in BASIC in class for years. I have fond memories of those gargantuan machines. I honestly couldn’t tell you a single thing I did in that class, though. It’s all gone from my memory, other than programming a Snake clone one afternoon.
More than likely, the Model III computers. The Model II computers has 8″ diskettes and no cassette port, and were intended solely for business use, while the Model III computers had 5¼” diskettes, no detached keyboard, and supported cassettes.
