was Tandy Corporation's desktop microcomputer model line, sold through
Tandy's Radio Shack stores in the late 1970s and early 1980s. The first
units were rolled out to the
stores the third week of December 1977. The
line won popularity with hobbyists, home users, and small-businesses.
leading position in what ''Byte'' Magazine called the "1977 Trinity"
(Apple, Commodore and Tandy) had much to do with Tandy's retailing the
computer through more than 3000 of its Radio Shack (Tandy in Europe)
storefronts. Notable features of the original TRS-80 included its
full-stroke QWERTY keyboard, small size, its Floating Point BASIC
programming language, an included monitor, and a starting price of $600.
The pre-release price was $500 and a $50 deposit was required, with a
money back guarantee at time of delivery which was a bit of a steep
price. One major drawback of the original system was the massive RF interference it caused in surrounding electronics, violating FCC regulations. This lead to the Model 1's phase-out in favor of the new Model III.
