Livermore Time Sharing System
Encyclopedia
The Livermore Time Sharing System (LTSS) was a supercomputer
operating system
originally developed by the Lawrence Livermore Laboratories for the CDC 7600
series of supercomputers.
LTSS resulted in the Cray Time Sharing System
and then the Network Livermore Timesharing System (NLTSS).

CDC 7600
The CDC 7600 was the Seymour Cray-designed successor to the CDC 6600, extending Control Data's dominance of the supercomputer field into the 1970s. The 7600 ran at 36.4 MHz and had a 65 Kword primary memory using core and variable-size secondary memory...

Cray Time Sharing System
The Cray Time Sharing System, also known in the Cray user community as CTSS, was developed as an operating system for the Cray-1 or Cray X-MP line of supercomputers. CTSS was developed by the Los Alamos Scientific Laboratory in conjunction with the Lawrence Livermore Laboratory...
