We have a VAX 11/785 which is running VMS 4.7 right now.  It talks to
some Symbolics workstations over an Ethernet via the DEC Ethernet
controller and DECnet.  It also has an Excelan Ethernet controller
attached to the same Ethernet, through which it talks TCP/IP to
some (~30) Suns and a gateway to the Internet.  The applications on the
system are mostly databases and development and testing of
scientific libraries for data analysis (lots of Fortran compilation).

Our environment seems to be going toward Unix derived operating 
systems.  The replacement for our Cyber 205 will probably be required
to have some form of Unix on it.  We want to be able to run NFS,
X Windows, etc., on the VAX in the near future, besides what we use
it for now.

We're thinking of moving from VMS to Ultrix.  Has anyone out there
done this recently?  What are the pitfalls?  What can you do under
VMS that you can't under Ultrix, and vice versa?  Will it adversely
affect what we use the VAX for now?  Etc., etc...

Any info would be greatly appreciated.  Please mail any responses
because I don't read this group regularly.  Send responses to

Thanks again.
