So, anybody got a system running from that tape yet?
(Other than me :-)
Does this count? I named it bill because I wasn't sure which version it
was :)
And I did it from tape, not RX-50s and swapping 31 of them in/out with
simh... And I couldn't get 11/73 to work (I think my simh has a regression
there), but 11/83 worked just fine.
Interesting. In the last couple days I have done 11/73, 11/83 and
11/44. All worked fine.

Nothing wrong it does that. I don't think it goes away until after
you build a new custom kernel. You will need that for networking
anyway. Hope your good with overlays. :-)

ULTRIX-11 Kernel V3.1

(and I think my simh is a bit wonky because it doesn't quite work: it
hangs from time to time, but only after a reset)
Mine has been stable so far. Doesn't really get unstable till you
add networking. :-)
I am running on this: PDP-11 simulator V3.8-1
Now that people have made me interested again I think it's time
to get the source loaded and look into what it takes to build
install kits on other media.
I never really did much with Ultrix-11 on SIMH, mostly on real
hardware. That's where I did all the testing when I first figured
out how to take the files from the archive and build a tape. The
original was TS02 but I later used Fred's setup to make the TK50.
Being as this is the only OS that can legally be used I would
expect more activity. First thing is to try and find my improved
date command that lets you set dates after 1999. :-)
Wish we had a list for Ultrix-11 specifically. Might be a lot of fun.
