The Network Livermore Timesharing System (NLTSS, also sometimes the New Livermore Time Sharing System and internally as LINOS, the LINCS Interactive Network Operating System) is an operating system that was actively developed at Lawrence Livermore Laboratory (LLL) (now Lawrence Livermore National Laboratory, LLNL) from 1979 until about 1988, though it continued to run production applications and be supported and even, in some cases, extended until 1995. A previous operating system, the Livermore Time Sharing System had been developed over a decade earlier at LLL.
NLTSS ran initially on a CDC 7600 computer, but only ran production from about 1984 until 1995 on Cray computers including the Cray-1, Cray X-MP, and Cray Y-MP models.
