The TRS-80 Micro Computer System (TRS-80; later known as the Model I to distinguish it from successors) is a desktop microcomputer launched in 1977 and sold by Tandy Corporation through their Radio Shack stores. The name is an abbreviation of Tandy/Radio Shack, Z-80 microprocessor. It was one of the earliest mass-produced personal computers.
By 1979, the TRS-80 had the largest selection of software in the microcomputer market. Until 1982, the TRS-80 was the best-selling PC line, outselling the Apple II series by a factor of 5 according to one analysis.
In mid-1980, the broadly compatible TRS-80 Model III was released. The Model I was discontinued shortly after, primarily due to stricter FCC regulations on the radio-frequency interference it caused in surrounding electronics. In 1983, the Model III was in turn succeeded by the compatible Model 4.
TRS-80 is the name of Tandy Corporation's original 1977 microcomputer system (also known as the Model I). The TRS-80 brand was also later applied to many different computers sold by Tandy, including several unrelated in design to the Model I.

Biography
TRS-80 was started by Kent Rayhill and Jay Rajeck in their hometown of Chicago, with Deb Schimmel joining them early on. The trio shared a common desire to write and perform music with real drums and synthesizers. A music writing frenzy of over 50 songs took place at Rajeck's home studio. The band played their first live show in 1998, opening for Death In Vegas at Double Door in Chicago. The band was known for their incorporation of visuals projected in sync with their music during live performances.
Chicago indie rock venue The Empty Bottle took TRS-80 under their wing shortly after hearing the band's demo and put them on the bill with artists like Sonic Boom, Acid Mothers Temple, Oval, and Laika among others, which helped grow TRS-80 a local following. From there they received bigger shows at venues like Metro, the Vic Theater and the 2,500 seat Riviera Theater opening for B52s, The Sisters of Mercy, The Creatures and other touring bands.
