EMAS, The Edinburgh Multi Access System, is a mainframe operating system which was designed around the time of Multics, and before the days of Unix, which was not only innovative for its time, but remained well ahead of the pack for years.
One of the primary drivers for this project was that there were significant software engineering lessons learned in the EMAS project which seem to have been forgotten. With luck this site will help some of our younger innovators avoid reinventing the wheel again.

AN EXPERIMENT IN DOING IT AGAIN, BUT VERY WELL THIS TIME - Software engineering lessons learned in the re-implementation of EMAS from the 4/75 to the 2900.
