With thanks to Paul Laughton, in collaboration with Dr. Bruce Damer, founder and curator of the DigiBarn Computer Museum, and with the permission of Apple Inc., we are pleased to make available the 1978 source code of Apple II DOS for non-commercial use. This material is Copyright © 1978 Apple Inc., and may not be reproduced without permission from Apple.
The Apple II, first released in 1977, was a ready-to-use computer with a keyboard, and could be hooked up to a diplay monitor. It was priced at $1,298, and featured color graphics, expansion slots, and built-in BASIC programming language.
The Apple II DOS source code was developed over the span of seven weeks by Paul Laughton, a contract programmer from Shepardson Microsystems. The DOS was written on punch cards, which would then be read into a National Semiconductor IMP–16 and assembled, and a paper tape produced. The paper tape was read into an Apple II via a plug-in card created by Apple co-founder Steve Wozniak.
The source code is downloadable from the Computer History Museum website, and includes meeting minutes between Apple and Shepardson Microsystem, plus contracts and scanned printer listings from 1978.
