	The card I believe was called a DEUNA which was the unibus precursor to
the infamous DEQNA q-bus DECNET/ETHERNET interface. They connected to
thickwire ethernet using an H4000 or a DELNI port.  You could probably still
find them but I wouldn't guarantee that they would work anymore. At least
not with DECNET.  I think they tried to phase out all the DEQNA's due to some
hardware incompatibility with the evolving spec's to DECNET.  I can't be
really certain of this as there were problems with RSX11M decnet software
and incompatibilities with new VMS releases.  I kept a DEQNA going on an RSX
system right up until the router went to VMS 5.3 though. The same may
have been true for the DEUNA's as well.  They were very early network
technology and were big, fat and ugly to look at.
