I always have liked the following:

        Micro: can sit on a desk
        Mini: doesn't require special power or cooling/airconditioning
        Main: requires special power and cooling

I see the original poster apparently wants to classify all VAXen as either
Mini's or Main's. Sorry, but I've got VAXen that are a lot smaller than
some of my PC's/Mac's. OTOH, I wouldn't call my VAXstation 4000/VLC a
Micro, I'd call it a Workstation :^)

Now there is a definition that's gotten really grey, the difference between
a Micro, a PC, and a Workstation.

Let's face it, no one is going to come up with an answer that everyone
agrees with.
