Edinburgh Multiple Access System

The Edinburgh Multi-Access System (EMAS) was a mainframe computer operating system developed at the University of Edinburgh during the 1970s. EMAS was developed because none of the manufacturers' operating systems (nor independent systems such as Multics) came close to satisfying the demanding performance requirements of Edinburgh University. The Edinburgh Computer History Project is attempting to salvage some of the lessons learned from the EMAS project and has the complete source code of EMAS online for public browsing.
