TRS-80 was Tandy Corporation's desktop microcomputer model line, sold through Tandy's RadioShack stores in the late 1970s and 1980s. Hobbyists, home users, and small-businesses were the intended consumers, and the endearment of the TRS-80 computer by its users resulted in a successful venture for Tandy Corporation. Its leading position in the 1977 Trinity years was mostly due to Tandy retailing it through more than 3000 of its Radio Shack storefronts, (Tandy in the UK). Its other strong features were its full-stroke QWERTY keyboard, its small size, its well-written Floating BASIC, an included monitor, and a price of $599.
One major drawback with the original Model I was the massive RF interference it caused in surrounding electronics. This became a problem when it violated FCC regulations, leading to the Model I's phase out in favor of the new Model III.
By 1979, the TRS-80 had the largest available selection of software of the microcomputer market.
