Welcome to the '''Tandy / Radio Shack''' category! Tandy was one of the founding US home-computer manufacturers, selling its [[TRS-80 Model I|TRS-80 Model I]] (1977) and the [[TRS-80 Color Computer|Color Computer]] (CoCo, 1980) line through thousands of Radio Shack stores. The [[TRS-80 Model 100|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.
Welcome to the '''Tandy / Radio Shack''' category! It is for repair guides for Tandy and Radio Shack computers: the TRS-80 desktops, the Color Computer, the Model 100 portables, the Tandy 1000 and later PC compatibles, and the pocket computers. [[Tandy TRS 80]] explains how the TRS-80 families differ.


Each system features:
Greyed entries in the tables below have no page yet.
* 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
