Welcome to the Tandy / Radio Shack category! Tandy was one of the founding US home-computer manufacturers, selling its TRS-80 Model I (1977) and the Color Computer (CoCo, 1980) line through thousands of Radio Shack stores. The Model 100 (1983) was the first true notebook computer to sell in large numbers, and the Tandy 1000 family (1984-1993) was the dominant home-PC-compatible line through the late 1980s. This category covers TRS-80 Z80 desktops, the entire CoCo line, the Model 100 portables, the Tandy 1000/2000/3000/4000 PC-compatibles and the TRS-80 Pocket Computer family.

Each system features:

Maintenance of the cassette and 5.25" floppy mechanisms used throughout the TRS-80 line
CoCo composite-out, RGB-mod and SuperFloppy upgrade work
Model 100 LCD ribbon repair and BlueChip / REX flash documentation
Tandy 1000 PSU service, capacitor replacement and floppy alignment
