The RadioShack TRS-80 Color Computer, later marketed as the Tandy Color Computer, is a series of home computers developed and sold by Tandy Corporation. Despite sharing a name with the earlier TRS-80, the Color Computer is a completely different system and a radical departure in design based on the Motorola 6809E processor rather than the Zilog Z80 of earlier models.

RadioShack is an American electronics retailer founded in 1921. It was established as an amateur radio mail-order business centered in Boston, Massachusetts. Its parent company, Radio Shack Corporation, was purchased by Tandy Corporation in 1962, shifting its focus from radio equipment to hobbyist electronic components. At its peak in 1999, Tandy operated over 8,000 RadioShack stores in the United States, Mexico, the United Kingdom, Australia, and Canada.
