In the first month after its release, Tandy Radio Shack's first desktop computer -- the TRS-80 -- sold 10,000 units, well more than the company's projected sales of 3,000 units for one year. Priced at $599.95, the machine included a Z80 based microprocessor, a video display, 4 kilobytes of memory, BASIC, cassette storage, and easy-to-understand manuals that assumed no prior knowledge on the part of the consumer.
