on vintagecomputer.net I documented a lot about the help I got to get my
3100 up and running. I'd suggest you take a look there, includes tips from
cctalk that I assembled plus my own findings from manuals and trial and
error to get up and running. Search "MicroVAX 3100" - warning organization
is haphazard at times but there is a lot of useful stuff if you dig around.

Alright, so the 3100 arrived yesterday afternoon and
looks to be in good
condition visually. The voltages from the PSU look ok as well. So I plugged
things back in and powered it on.
I don't have a console for it yet, but it seems to go through some
self-test, the tape drive does
some stuff as well as the hard drive. It came with the slightly larger RZ25
rather than the RZ23.
I am getting some 6-conductor cable soon and will make a console cable
for it. I'm very curious
to see what it does on the console.
I have a SCSI CDROM coming in a few days. I also have an old SUN external
enclosure that I'll put to use for it as an external CDROM.
Interestingly, it doesn't have a model number on the sticker, but based on
what I have seen, and
the pattern of the connectors in the back, I am pretty sure it is a model
10.

Which 3100?
There are some very low performance 3100 at the lower end, and the
best(?) 3100/105 or 3100/95 still fetch some serious money.
My recommendation is usually the pizza box 4000/vlc ...
Specially, if you don't know what you need it for :)
