If you look at (almost?) any document
produced by Digital in PostScript format,
somewhere near the beginning you should
find the part that does the Digital
logo. Usually there is a long comment
describing who designed it, when it was
done and how it should (and should not)
be used.
At some late stage in its life, Digital
decided to revamp the logo. For a mere
$500K (or thereabouts IIRC) a consultancy
recommended some major changes. The round
dot is the most noticeable. For $400K
I would have been happy to provide equally
valuable advice ... as usual I was in the
wrong place at the wrong time :-)
