I personally would not prefer a stripped down SR10 for systems under 2 or 3
MB.  I just want to know what to expect as far as performance doing the
typical things that typical sites use DSP's for (...yes...I know all sites
are different...just tell us what the estimate is based on so we can
extrapolate to OUR configurations).

...what I was really asking for was a typical set of things that a 2 or 3 MB
file server can really do without being ridiculously slow at SR10...

Right now, they are the main file servers for their rings, they are the TCP
gateway, they run the print server, they have the 1600 bpi tape drive, and
lots of users are on there (hey...that's why it's called a file server :-) )

I can move the TCP stuff onto an AT-bus system and let the same system be
the gateway for ring-ring  AND TCP traffic (cost about $1500)

I can get a 8mm drive to remove the need for the 9 track tape (I am probably
going to do that anyway and I figure thatrunning the tape drive on 2nd shift 
to do backups is no big deal anyway )

I *could* buy a AT-bus parallel printer interface board likethe one in the
file server( I guess about another $1500) but I really don't want to.

That would leave me with the file server just serving files.  Can I do THAT
on 3 MB ??? Also, I seem to remember that the computing requirements for a
network access of files will be to the receiving node at SR10...in other
words, if I use the file server as a file server, its load at SR10 will be
higher than the load at SR9 (not to mention the load imposed by the new OS).

What I really wanted to know is "can I run the file server as a TCP gateway,
run a print server (and an X-server but that's probably dreaming...) and let
it be my primary file server for the ring with "reasonable" response?
