Although developed independently, Unix pipes are related to, and were preceded by, the'communication files'developed by Ken Lochner in the 1960s for the Dartmouth Time Sharing System.

Digital Equipment Corporation developed many operating systems for its various computer lines, including TOPS-10 and TOPS-20 time sharing systems for the 36-bit PDP-10 class systems.
23.
Initially developed in a 6502 assembler running on the Multics time sharing system, VisiCalc was ported to numerous platforms, both 8-bit and some of the early 16-bit systems.
24.
This led to the MCTS system, " Multiple Console Time Sharing System ", a version of Multics adapted for their own use, which they developed on the CDC STAR-100 computer.
25.
The "'Multiple Console Time Sharing System "'( MCTS ) was an operating system developed by General Motors Research Laboratory in the 1970s for the Control Data Corporation STAR-100 supercomputer.
26.
Access to the computers themselves was also extended to more people by systems such as the Dartmouth Time Sharing System ( DTSS ), which connected several thousand users through many remote terminals to a central mainframe computer.
27.
Its IDE ( part of the Dartmouth Time Sharing System ) was command-based, and therefore did not look much like the menu-driven, graphical IDEs popular after the advent of the Graphical User Interface.
28.
These commands were often believed to be part of the BASIC language by users but in fact they were part of the time sharing system and were also used when preparing ALGOL or FORTRAN programs via the DTSS terminals.
29.
Its first product was the "'Supertek S-1 "', a compact, air-cooled, CMOS CTSS ( Cray Time Sharing System ) operating system, and later a version of Unix.
30.
When SDS realized the value of the time sharing system, and that the software was in the public domain ( funded by the US federal government ), they came back to Berkeley and collected enough information to begin manufacturing.
