The last release of Ultrix was something like 4.6 (I'll have the

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.
