Radio Shack TRS-80 Model III
Radio Shack TRS-80 Model III.
More advance that the 1st model, huh…?
Yup… this model is basically an upgrade of the Model I, which was released three years earlier.
The main different between the 1st model and the 2nd model is it is faster, has more memory, and the floppy drives hold twice as much data. But… it’s still using the same CPU like the 1st model.
Lets take a look to this model and its specifations.
