Compaq, who recently merged with Digital, has decided to take a page
from DEC's old, musty, dusty yet industry-fashionable playbook of
renaming one's OS.  If you don't recall, OSF/1 became Digital Unix a
while ago, and sometime before that VMS was re-christened OpenVMS.
Now, PC week (Jan 18, 1999) reports the following:

"Compaq is expected to make more Unix news next month when it renames 
Digital Unix to Tru64Unix (sic), according to sources."
