Aha! It has an H7821-00 180W PSU which makes it a Model 10. So now I know
for sure.

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.
