Unix (officially trademarked as UNIX® - the documentation switched from using 'UNIX' to 'Unix' as of V7) 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 1 - The first version of UNIX that has been recently made to run on the PDP-11
- UNIX V5 - One of first version with known source and binaries available.
- UNIX V6 - The last version before branches started to appear
- Unix V7 - One of the most complete and the last generally available and PDP-11 version of Research UNIX
- Unix/32V - A 32bit port of System 7 to the VAX 11/780.
Unix then went commercial and was sold. Below is an early ad for AT&T UNIX.
CSRG releases
Meanwhile the CSRG kept on releasing newer BSD UNIX's derived from 32v.
- 2.11 BSD - A still-maintained version for PDP-11s
- 3.0 BSD - Derived from 32v, including a real virtual memory system
- 4.0 BSD - A vastly improved 3.0
- 4.1 BSD - These were mostly betas testing new filesystems & the TCP/IP protocol.
- 4.2 BSD - The first shipping version of BSD with TCP/IP, FFS & termcap for the VAX.
- 4.3 BSD - A version of pre-POSIX BSD, for the VAX.
- 4.4 BSD - Did this version ever ship?
- Net/1 - The TCP/IP source, and other programs free of the AT&T copyrite
- Net/2 - Almost an entire release of all the source. This was the contention in the AT&T vs CSRG lawsuit.
- 4.4 BSD Lite - This was the result of the aformentioned lawsuit. This was 'lite' in that it removed the offending 6 files.
386 BSD This is the first Net/2 derived OS that then spawned the Net/FreeBSD os's.
FreeBSD focuses on providing a system geared towards a single user.
NetBSD will run on a variety of 32-bit older systems from the VAX to the Amiga.
OpenBSD derived from the NetBSD project will run on all kinds of systems.
