Hi !

I had such a 3100 some time ago. It was a VAXstation 3100m30, and as i
knoe they all are m30 or m40 (same machine, different enclosure), if there
is no special model number.

Difference to the m38: m30 is a bit slower (2.8 vs 3.8 VUPs), and maybe
the onboard memory differs. (Can't say exactly, if mine had a 8 MB or a 12
MB modules installed, it was 16 MB full RAM.)

so long... Michael
