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.  :-)

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.
