The MicroVAX II CPU is a single chip (CVAX), with a second support
processor (FPU?,MMU? I forget). Runs on 110V wall socket. The BA23?
pedestal cabinet could be rack-mounted in about 6" of a 19" rack
(with two internal drives)
The MicroVAX 2000 CPU is the same CVAX chip in a smaller box yet
13"x13"x5" or so.
The MicroVAX 3100/xx CPU is a faster (3x) chip in a box more like
the modern PC desktop case (short and wider, but similiar)

There are lots of ways to "slice" this
question. I have at various time used:
if it runs on one 110V wall socket its a micro
if it takes 220 and/or three phase its a mini
My, I've suddenly got a whole lot of minis around here! Thre only exception I
can think of is my DECstation 5000/200, which for some reason seems to be
stuck in 110V country.
if the "CPU" is one chip its a
micro
BTW, how micro is a MicroVAX?
