The time-sharing monitor system

Abstract

The IBM Advanced Systems Development Division is currently operating the Time-Shared Monitor System (TSM), an experimental, general-purpose, time-sharing system based on the IBM 7090 Data Processing System. This system is capable of serving 24 remote users simultaneously. It requires a minimum of computing equipment, and gives the remotely located user a maximum amount of control over the 7090 itself; and over the content of his program files within it.
