My time playing with Pro's faded out before Venix 2 was available (free)
for me to try.  I've played a fair bit with Venix 1.1 on both Pro 350's
and Pro 380's.  The Venix 1 series I feel is basically V6 derived while
I understood the Venix 2 series was derived from Sys III.

About a year ago Rick Macklem that did a port to the Pro series mailed
me his "Pro stuff" which included a tape and floppies.  I've forgotten
what all is in that stash, but taking a peek at some old mail he mentions:

I had thought his set of patches were in the PUPS archive.  In fact I
see the patches under PUPS/Distributions/ucb/2.9-pro350.
