TRS 80 Model III

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.
