Description

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Edinburgh Multi-Access System (EMAS) was a mainframe computer operating system developed at the University of Edinburgh, Scotland, 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. Originally running on the ICL System 4/75 mainframe (based on the design of the IBM 360) it was later reimplemented on the ICL 2900 series of mainframes (as EMAS 2900 or EMAS-2) where it ran in service until the mid 1980s. Near the end of its life, the refactored version was back-ported (as EMAS-3) to the IBM XA architecture again, running on Amdahl 470 and NAS VL80 IBM mainframe clones into the early 1990s. It was a powerful and efficient general purpose multi-user system which supplied all the computing needs of Edinburgh University and the University of Kent (the only other site outside Edinburgh to adopt the operating system). The final EMAS system (the Edinburgh VL80) was decommissioned in July 1992.
