TRS-80 was Tandy Corporation's first microcomputer model, with Zilog's Z80 8-bit CPU. TRS-80 was sold through Tandy's Radio Shack stores in the late 1970s and early 1980s. MicroChess, by Peter Jennings, was the first commercially-available microcomputer-based chess program running on a TRS-80, soon followed by Sargon, written by Dan and Kathe Spracklen.
