Here at Ames, we are running both TCP/IP and DECNET on an 11/780 using
Ultrix. There have been no problems that I am aware of.

Yes, it works fine. We have tested Ultrix with the Annex. No problems.

This is good reasoning in my opinion.

I have no experience with the 8350. Sorry. We do have an 8650 running VMS, and
I have been impressed by its speed.
