No one ever called it a "Digital Ethernet Personal Computer Bus
Adapter", just a DEPCA. I never previously knew that there was any
meaning behind the DEPCA name.

I have a DEPCA in a 486 box that I got set up a while ago with some
version of DECnet DOS, or Pathworks, from here, I forget which version
without setting it up to take a look:

Over 30 years ago I worked on PC DECwindows for DOS for a couple of
years. There were Rational 286 and PharLap 386 DOS Extender versions.
The DECnet DOS development was in a different group in a different
building. The PC DECwindows for DOS server used DECnet DOS as a
network transport.
