The Multicians web site presents the story of the Multics operating system for people interested in the system's history, especially Multicians. The site's goals are to
- preserve the technical ideas and advances of Multics so others don't need to reinvent them.
- record the history of Multics, its builders, and its users before we all forget.
- give credit where it's due for important innovations.
- remember some good times and good people.
The Multicians web site contains 449 HTML files (see the Site Map) comprising over 1,000,000 lines, 49 PDF files, and 440 graphic images. The site has benefited from the contributions of many authors. Contributions are invited: if you have a correction, fact, date, name, anecdote, or picture, please share it with Multicians everywhere by sending mail to the editor.
Multics (Multiplexed Information and Computing Service) was a mainframe timesharing operating system begun in 1965 and used until 2000. Multics began as a research project and was an important influence on operating system development. The system became a commercial product sold by Honeywell to education, government, and industry.
Multics was a prototype of a Computer Utility, providing secure computing to remote users at their terminals. Multicians still miss the elegant, consistent, and powerful programming environment; some Multics features are only now being added to contemporary systems.
