TRS 80 Model III ( Model Number: 26-1062) - 02 |
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) |

TRS 80 Model III-02: Bought in Schepdaal (Brussels), together with lots of other stuff on 11/07/2002. This is a list of the things I bought in Schepdaal: Tandy TRS80 Model III 16Kb RAM Tandy TRS80 Coco2 16Kb Ram (26-3026) Tandy TRS80 Coco2 64Kb Ram (26-3003B) Tandy multi pak interface Double disk drive and lots of diskettes Datasette with lots of cassettes Lots of cartridges 2 Tandy Deluxe and 1 other joystick Tandy Mouse 2 Self made kits (80 column screen and disk drive interface) Videopac G7000 26 Videopacs C7010 Chess Module C7420 Home Computer Module Some Manuals Paid 100€ Actually this collection was a tip from the guy in Wervik, he didn’t have the time to go to Schepdaal and so we made a deal. I would buy the stuff and give him the Videopac with the games. One problem though: the videopac didn’t work, I gave him one of mine and I got a Tandy TRS80 200 Laptop. Good Guy ! When I unpacked everything I noticed I didn’t got the Chess and Home Computer Module. I collected them on 15/07/2002 |
