I have 3 MicroVAX 3100 Model 30s given to me by someone who is leaving the
country and could not take them with him. I took them rather than see them
discarded. They each have 8Mb onboard memory. They do not have any disks and
the cover on the storage bay is missing. One of them has a little bit of
damage to the rear plastic panel.
I cleaned out all the dust and powered them up, they all booted to the
console prompt just fine.
They are in Greater Manchester, England.
Regards
Rob
