              The last release of Ultrix was something like 4.6 (I'll have the
              check
              my notes, but I'm traveling) - and on PMAX and VAX.


      V4.5 was the last.

Ok, that sounds right, I remembered that their was something post the
R4000 work (V4.4), but I'd forgotten how many.


I think V4.5 only came about because of some Y2K issues. I don't think there
was anything else meaningful in there as compared to V4.4.


              Over the course of time, Ultrix ran on:     PDP-11 models with a
              MMU both
              with and without separated I/D space, most of not all of the Vaxen
              (except for the 9000 I believe), and MIPS 2K,3K,4K systems that
              Digital
              made.


      Actually, if I remember right, the 9000 is supported by Ultrix.
      However, the 7000/10000 systems are not. But I might also be
      remembering things wrong.

I think you are remembering correctly on both accounts.     I remember
their was a push by the OS team to decommit Ultrix in favor of what
would become Tru64 (aka OSF/1) started around that time.


Sounds likely. I bet there was some interesting times at that point.

Also, Ultrix-11 don't have a strong relationship with Ultrix that runs on
VAXen or Mips machines.

Hello!
I remember discussing with a DEC sales 'droid regarding a supposed non
Intel running variety of Windows that was coming really soon now. It
was supposed to become Windows NT. The first release was on an Alpha.
Not the blue skinned variety of machines, but the classic white box
one as demo. That came about as I was studying a MIPS based
workstation running Ultrix on it. And remember this was at UNIX World
a really long time ago. And that demo surfaced some time later. The
big complaint was that when too many windows were open the system
started dragging its feet.

I was more interested in Ultrix on MIPS support then NT support on it.

Incidentally Cory and Dave the monsters are off this week. Something
about a union meeting else where.
