Wrong. I managed to get that state several times while hacking Linux
on VAX, with probably any desktop-sized models (inkluding the smaller
3100, as well as 4000/60, /90, /90a and /96).

Could be. But I've never ever had seen the heat sinks to get that warm
that I thought about thermal problems.

The /90a (12ns = 83MHz) is a bit faster than the /90 (14ns =
74.43MHz). The numbers are taken from Wikipedia.
