Have you been able to acquire the documentation for the DECNA card?  I
think that is roughly what it is called.  The Pro Ethernet card.  A few
old timers like myself and Dan Lanciani talked years ago about running
things on a Pro and no-one seems to know much about this relatively
critical bit of documentation.  Again referring to Rick Macklem's
correspondence (I believe I was asking him, again, about these docs):

The rumors we were able to find all pointed to this place and person
WRT documentation for the ethernet card.
