Multiplexed Information and Computing Service

Multicians.org is a volunteer-run archive documenting the history of the Multics time-sharing operating system, contributed to by former Multics developers and users. It hosts hundreds of HTML pages, PDFs, and images covering Multics history, biographies of Multicians, technical papers, myths, and a site timeline, and links to an open-source Multics simulator hosted at MIT. Content is community-contributed, with corrections and anecdotes invited from Multicians worldwide.
