The Michigan Terminal System (MTS) is one of the first time-sharing computer operating systems.[1] Created in 1967 at the University of Michigan for use on IBM S/360-67, S/370 and compatible mainframe computers, it was developed and used by a consortium of eight universities in the United States, Canada, and the United Kingdom over a period of 33 years (1967 to 1999).[2]
