- 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.
