What Wikipedia says

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.
