Everything about Apple DOS

Family of disk operating systems

Apple DOS is a disk operating system (DOS) used by the Apple II series from 1978 until 1983, when it was superseded by Apple ProDOS. It had three major releases: versions 3.1, 3.2, and 3.3. When Apple Computer introduced the Apple II in 1977, it included Integer BASIC but lacked a DOS. Users could enter and run programs in BASIC and store programs and data on compact cassette tapes. Steve Wozniak, Apple's co-founder, designed the Disk II controller in 1977. However, with a tight deadline and limited experience developing a DOS, Apple hired an outside company to create one. After considering Digital Research's CP/M, Apple contracted Shepardson Microsystems on April 10, 1978, to develop Apple DOS for US$13,000, with delivery scheduled within 35 days. Apple supplied detailed specifications, and employee Randy Wigginton worked with Shepardson's Paul Laughton during development. Laughton wrote the software using a minicomputer and punched cards.
