The Multiple Console Time Sharing System (MCTS) was an operating system developed by General Motors Research Laboratories in the 1970s for the Control Data Corporation STAR-100 supercomputer. MCTS was built to support GM's computer-aided design (CAD) applications.[1]
MCTS was designed starting in 1968. It was written in a high-level systems programming language "Malus", a dialect of PL/I. A superset of Malus called Apple became the primary application language.[2]
MCTS was based on Multics.[3] All access to data was through the virtual memory system. Only the system paging support module was concerned about the physical location of the data.[2]
