TL;DR
The design objectives of CP-67/CMS are described, a multi-access system that manages the resources of a computer set up for time-sharing such that each user appears to have a complete, dedicated computer at his disposal.
Abstract
Time-sharing systems are now an important factor in the computer industry. Because they allow a multiplicity of users to have access to a computer by means of a terminal, they encourage increasing numbers of people to utilize computers. Thus, various ways of increasing the capability of a computer in this area are being sought. One such system is the Control Program-67/Cambridge Monitor System (CP-67/CMS), a multi-access system that manages the resources of a computer set up for time-sharing such that each (remote) user appears to have a complete, dedicated computer at his disposal. This concept is known as a virtual machine and allows each user to select the operating system he wishes to run because concurrent operation of several operating systems is possible.
