Ultrix == Unix

[Bob Devine]

  I wrote that "Berkeley runs Ultrix on its department machines
because of the support available."
 
  Sorry, that is wrong.  UCB has Ultrix on those machines, instead
one of its releases such as 4.2 or 4.3, because they are VAX 8800's
and the CSRG didn't want to bother with the mods needed for those boxes.
Why UCB bought the machines instead of ones that did easily run 4.3
came from a decision that was apparently more political than technical.

  The reason put forward by sun!david, that there was a licensing
problem from AT&T for those machines, seems unlikely.
