The system is a symmetric multiprocessor with shared physical and virtual memory. Elliot Organick 's book, The Multics System, an Examination of its Structure , describes the system as it was in about 1968. MIT started providing timesharing service on Multics to users in fall of 1969. GE sold the next system to the US Air Force , and the military use of Multics led to some of the system's security features. Honeywell sold more systems to government, and to auto makers, universities, and commercial data processing services.
None are still in use.
Honeywell decided not to create a new hardware generation for Multics in the mid-80s and stopped developing the operating system. Subsequently, Honeywell sold its computer business to Bull, which also chose not to build new Multics hardware, and all sites replaced their Multics systems with more modern hardware. Convenient remote terminal use. A wide range of system configurations, changeable without system or user program reorganization. A high reliability internal file system .
