Re: Perkin-Elmer Unix

	As of about a year ago (when we looked at a bunch of 32-bit mini's here
at RIT), PE did NOT have virtual memory.  The sales force, of course, touted
this as a "feature", as programs would not be delayed while their pages were
retrieved off of a slower, secondary device.  This, coupled with their
backplane capacity of 64Mb/sec, led us to believe that they were more oriented
toward process control and data acquisition environments, where the delays of
page faults could not be tolerated.

	Note that this was the case with their own OS (which I have heard is
terrible from others on the net), but it's not likely that the hardware folks
implemented stuff that the software doesn't use.  This suggests that version
of Unix running on the machine also lacks virtual memory.
