Gift of K.S. Widelitz
In the early 1970s, most personal computers came as hobbyist kits requiring a high level of technical expertise to assemble. Don French, a buyer for the consumer electronics chain Tandy Radio Shack (TRS), believed that Radio Shack should offer an assembled personal computer and hired engineer Steve Leininger to design it. In the summer of 1977, Radio Shack introduced the TRS-80 for $599. This offering included a BASIC language interpreter, four kilobytes of RAM, a Zilog Z80 processor at 1.77 megahertz, a twelve-inch video monitor, a cassette recorder, a power supply, and a cassette tape containing the games Blackjack and Backgammon. While some Tandy executives were skeptical about the success of the PC market, the availability of the TRS-80 on five thousand Radio Shack store shelves helped the Model 1 sell over one hundred thousand units during its first year, which was 50 percent of the total PCs sold in 1978.
The TRS-80 had its microprocessor inside its keyboard. While you could purchase just the TRS-80 for $400, most opted for the package that included the twelve-inch monitor and cassette recorder for $600. This object includes the TRS-80 Expansion Interface for $299 (below monitor) that gave the machine an extra thirty-two kilobytes of memory; the TRS-80 Telephone Interface II for $199 (far left) that allowed for network communication; two Mini-Disk drives for $499 (right of monitor); and printer for $399 (far right).
