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, ordered unseen, were delivered in November 1977, and rolled out to the stores the third week of December. The line won popularity with hobbyists, home users, and small-businesses. Tandy Corporation's leading position in what Byte Magazine
called the "1977 Trinity" (Apple
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.
