TRS 80 Model III ( Model Number: 26-????) - 03 |
The model 3 is generally regarded as the successor to the Model 1. Its two 5.25" floppy disk drives can convert model 1 disks. However, It wasn't FULLY compatible with the model 1. There were differences in ROM which meant some programs had to be converted, especially those machine language ones that made ROM calls.

Does anyone know why ? |
