Help!!!

We here at OSU have just recently decided that we would purchase a VAX 8350 and
run ULTRIX on it.  We currently are running a VAX 11/780 with VMS.  We would
like to run DECNet to the two machines for file transferr, mail, etc. (our
first attempt at DECNetting anything).  We would then like to run a TCP/IP
link on the 8350 to do the terminal interface.  The first problem arises in
the fact that there are very few DEC people who know anything about ULTRIX,
much less TCP/IP.  This is also our first attempt at providing a campus wide
UNIX (at least a derivative) system, and also our first attempt at TCP/IP
networking.  In other words, we are stepping into unknown and previously
untouched areas.  To get on with it, my questions may be simple to you but
are still confusing to me.

Problem one.  Can ULTRIX, or 4.2 BSD (since it is supposedly not changed by
DEC) support both a DECNet link and a TCP/IP link at the same time without
problems?

Problem two.  Does ULTRIX do very well talking to terminal servers such as
the ANNEX UX on TCP/IP?

ETC.  Knowing that the 8350 is a BI bus machine, and that it comes configured
with one BI to Ethernet adapter, does DEC sell this adapter as a seperate
device?  I have only been able to find Unibus or Q-bus adapters.

The reason for going to the TCP/IP connection for terminals is based on the
fact that we don't want to lock ourselves into $'s of DEC hardware for
DECNet and then 2 years from now buy an ENCORE and find ourselves in
a real hole.

Are there other options that we are leaving out? Are we getting ready to
spend $'s only so that we can screw ourselves?  Does anyone out their
run a machine that has the dual connections discussed?  Is there some
other way that we haven't thought of that we are going to screw ourselves?
