From the further development of the MIT Compatible Time-Sharing System (CTSS), under the leadership of Fernando José Corbató , through his work in the field of multiple access computers, Multics emerged . It was in 1963 in cooperation with MIT, General Electric and Bell Labs of AT & T developed. In 1969 Bell Labs withdrew from the project. The development was financially supported by the ARPA . The system was in the programming language Early PL / I written (EPL), a subset of PL / I .
From 1969 the first Multics system was available at MIT. The first commercial system was sold by Honeywell Information Systems, Inc. on a Honeywell 6180 until the last system was installed in 1986. On October 30, 2000, the last running Multics system of the Canadian Department of National Defense in Halifax , Canada was shut down and taken out of service.
The only Multics installation in Germany was in operation from 1984 to 1991 at the University of Mainz .
