HARDWARE: COMPUTERS, PRINTERS, ETC

TRS-80 was a brand associated with several desktop microcomputer lines sold by Tandy Corporation through their Radio Shack stores. It was first used on the original TRS-80 (later known as the Model I), one of the earliest mass-produced personal computers. However, Tandy later used the TRS-80 name on a number of different computer lines, many of which were technically unrelated to (and incompatible with) the original Model I and its replacements.

In the early 1980's, Tandy began producing a series of computers that were "MS-DOS compatible" but not fully IBM compatible. The Tandy computer brand would continue through the release cycle for all remaining systems manufactured by Tandy.

Tandy released a large number of portable, notebook and laptop systems, beginning under the TRS-80 brand and then moving to Tandy branding.

Tandy and GRiD Systems combined and released several models under the GRiD label, which were in many cases simply rebranded versions of their Tandy-branded counterparts.

Tandy released a large number of printers, plotters, graphics tablets and other devices through the years.
