I haven't tried the 2.9 stuff at all on a Pro.  I have had it
running on an 11/23+ (w/binary license) for 10 years.  The
problem is the networking, as you have found.

Venix/Pro 1.1 and 2.0 run just fine on the Pro 380, and it's
pretty painless to install.  I have distribution disks for
Pro/Venix 1.1, but the install disk has apparently been
overwritten with the 2.0 installation disk.  And my distribution
for 2.0 is missing a couple of original disks; I have copies of
those disks, but they get read errors.

I guess the 2.9 stuff would be interesting if you got it to
work on the Pro, especially if you got networking to work.
I don't have any docs on the DECNA, but they must exist.  It's
probably pretty close to the DEQNA.
