Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The Universal Time-Sharing System (UTS) was an operating system for the XDS Sigma line of computers. UTS was announced in 1966, but because of delays did not actually ship until 1971. It was designed to provide multi-programming services for online (interactive) user programs in addition to batch-mode production jobs, symbiont (spooled) I/O, and critical real-time processes. The final version shipped in January, 1973. It was succeeded by the CP-V system, which combined UTS with the heavily batch-oriented XOS.
