I got this fragment from a timeline at

http://www.dimi.uniud.it/~miculan/Didattica/unix-history.html

Pretty intereseted. Fr 'instance, MS licensed and sold UNIX ( as "Xenix" ) in 1979, but.....well, read on.

1978 Bill Joy produces first Berkeley Software Distribution (BSD) of UNIX.

Ritchie and Steve Johnson complete first port of UNIX to an Interdata 8/32, the first non-DEC computer to run UNIX. Note that this is nearly ten years after running only on DEC equipment.

UNIX is ported to a DEC VAX, but not by Thompson and Ritchie, since they had become disenchanted by DEC and its unwillingness to support UNIX. DEC's refusal to support UNIX must be one of the all time great blunders of the computer industry.

The C Programming Language by Kernighan and Ritchie is published.

Doug and Larry Michels start Santa Cruz Operations, Inc. (SCO) to sell UNIX on a PC. By 1992, they grow to $175 million in revenues.

1979 Seventh Edition UNIX PROGRAMMERS MANUAL (UNIX Version 7) is published. It is the first edition without Thompson's or Ritchie's names. It is titled "UNIX (with a TM sign) Time-Sharing System." Bell Labs starts to protect its assets.

Microsoft licenses UNIX from AT&T and announces XENIX, which is soon overshadowed by MS-DOS.

1980 BSD UNIX finds its way back into Bell Labs as a new improved version.

Berkeley lands large DARPA contract and forms Computer Systems Research Group (CSRG).

SCO becomes a distributor for Microsoft XENIX and licenses the name XENIX because they sold their trade name DYNIX to Sequent.

1981 The IBM PC is released running Microsoft DOS; XENIX is pushed into the background.
