TRS 80 Model III ( Model Number: 26-?????) - 01 |
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. (www.old-computers.com) |
