The CSRG is better known as the University of California at Berkeley's Computer Systems Research Group.

This is the group that was responsible for CSRG BSD.

Not to mention biff, vi, and of course sendmail.

Notable people include Eric Allman, Marshall Kirk McKusick, Bill Joy..

An excellent overview of the history of the CSRG, as told by Marshall Kirk McKusick is available here.

Releases

The CSRG put together the following releases:

  • 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.
  • 4.1a BSD - This included BBN's TCP/IP software
  • 4.1b BSD - This version introduced the FFS file system.
  • 4.1c BSD - A beta of 4.2, and I think the first version of BSD sockets?
  • 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.
  • 4.4 BSD Lite2 - the last release?

386 BSD This is the first Net/2 derived OS that then spawned the Net/FreeBSD os's.
