Unix (officially trademarked as UNIX®) is a computer operating system originally developed in the 1960s and 1970s by a group of AT&T employees at Bell Labs including Ken Thompson, Dennis Ritchie and Douglas McIlroy. Today's Unix systems are split into various branches, developed over time by AT&T as well as various commercial vendors and non-profit organizations.
Versions of relevance for hobbyists include:
- Unix System 5 - The first version with known source and binaries available.
- Unix System 6
- Unix System 7 - One of the most complete and the last generally available and PDP-11 version of Research UNIX
- 2.11 BSD - A still-maintained version for PDP-11s
- 4.3-Quasijarus BSD - A version of pre-POSIX BSD, still maintained, for the VAX.
NetBSD will run on a variety of 32-bit older systems from the VAX to the Amiga. OpenBSD runs well on the VAX.
