Actually, thinking about it, it should be enough with just the boot file
that you are using.

Cool, thanks.
I figured out what's going on. The standalone programs are running,
they just aren't displaying any input or output after the first
character is printed. So if I do this:
--
sim> load -o boot 0
sim> run 2
--
and then blindly type "ra(0,0)vmunix", it boots!

Hmm hmm. I suspect I might know what is going on there. I'd have to
test and play around some to verify, though. The console I/O on the
86x0 machines are a bit special, and I wouldn't be surprised if
there were some issues in simh related to that.
Mark, can we get some trace of all reads and writes to the registers
related to the console? (There are four logical devices addressed on
the 86x0 machines through the same CSRs.)
Henry, if you could get such information logged, we could probably
fix this pretty fast. Or else if you could just provide me with the
files, I could test this myself as well. I don't have an old Ultrix
image around, though.

And I can then interact with the console, characters are displayed

The latest github code will no longer drop the last
character output
just prior to executing a HALT instruction which returns to the
"sim> " prompt.
Like I said above, nothing else changes though.
