DR's operating system, CP/M-86, was later shipped, but it was actually easier to adapt programs to DOS rather than to CP/M-86, and CP/M-86 cost $495. Microsoft (known mainly for their programming languages) were commissioned to write the operating system for the PC Digital Research failed to get the contract (there is much legend as to the real reason for this ). It was the first Tandy computer to support color graphics, and also supported cartridge programs and games, attempting to bridge both the home computing and video gaming markets.ĭevelopment of MS-DOS/ PC DOS began. Tandy released the TRS-80 Color Computer, based on the Motorola 6809E processor and using Microsoft BASIC as its programming language. The VIC-20 became the first computer to sell 1 million units. Also available were a number of games, a color plotter which printed on 6 in (152 mm) wide paper tape, and a graphics tablet (the KoalaPad). A 5¼" disk drive was available, along with a cassette storage system which used standard audio cassette tapes.

Magazines became available which contained the code for various utilities and games. Sinclair ZX80 was released for under £100.Ĭommodore released the VIC-20, which had 3.5 KB of usable memory and was based on the MOS Technology 6502 processor.
