The hardware scheme designed to implement an experimental IBM System/360, Model 40 time-sharing system will be discussed. The concept of a virtual system will be introduced which allows up to fifteen simultaneous users on the system, each user assuming he has a complete hardware-software of his own. The problem of building and interfacing a 64- word associative memory mapping device into an existing hardware system will be reviewed.
