Radio Shack personal computer model TRS 80 III, c. 1981. Introduced in August 1977 by the retail electronics chain Radio Shack, the TRS 80 was the first complete, pre-assembled small computer system on the market. The Level 1 basic computer came with 4k RAM, a monitor, a cassette and all the cables and adaptors needed and sold for $599.95.
