		+	Apple DOS was announced when Apple president [[Mike Markkula]] became dissatisfied with the [[Cassette\|audio cassette interface]] on the Apple II. At the executive board meeting in December [[1977]], he made a list of company goals. On the top of that list was "floppy disk". [[Steve Wozniak]] was to be the one to build a floppy disk drive and write a [[disk operating system]]. Wozniak did not know much about how floppy disk drives worked, but he once read a [[Shugart]] manual about how the drives worked. He then looked at an [[IBM]] drive to see how they correctly timed the read and write functions. They did it with complex circuitry. It was then when Wozniak realized that if he constructed the disk drives another way ("soft-sectored", the drive would self-synchronize), no circuitry was needed. They also did away with a little timing hole needed for IBM drives ("hard-sectored", this used the hole to tell what part of the disk was under the heads at any time).
		+
		+	Wozniak tabbed [[Randy Wigginton]] to write the disk operating system. They worked hard, trying to get everything completed by the Consumer Electronics Show 1978. They did, and by the first week of 1978 (the week the show was held), they had a completed drive, operating system, and demo disk. The information on the disk was accidentally lost when Wigginton suggested making a backup of it, but it was successfully recovered and everything went as planned.

'''Apple DOS''' was the name for the operating environment used on [[Apple II]] systems. However, the actual operating system was [[Applesoft BASIC]], or on older systems, [[Integer BASIC]]. ({{note|When Apple DOS loads, it loads Integer BASIC on a "language card" on newer Apple IIs.}})

== Release history ==
*'''3.0''': Beta version
*'''3.1''': First official release
*'''3.2''': [[Apple II Plus]] compatible.
*'''3.2.1''': Patch for the COPY utility; minor bug fixes
*'''3.3''': Hardware and disk upgrades, minor bug fix in 1983

Currently, it is unknown when Apple stopped support for DOS 3.3.
