How do you identify VAX/PMAX cpu's from software?

[Dan O'Neill]

Is there a way to determine the class of a VAX or PMAX cpu under
Ultrix?  We would like to be able to tell the difference between a
VAXstation 3200, VAXstation 3600, VAXstation 3100 and a DECstation
3100 (pmax) from within a program.  Any and all suggestions are
appreciated.
