Early UNIX Development

The UNIX Operating System was originally written by Dennis Ritchie and Ken Thompson at Bell Labs, beginning in 1969.

Originally written for the DEC PDP-7, it first became popular in 1975 with Version 6 (V6) on the DEC PDP-11. 


Users were programmers, who accessed the system with hard copy Teletype terminals, and later with CRT “Dumb Terminals.”
