That is expected. If you actually do this, you are expected to actually
have the *system* on an RL02, that you will be booting from. As the
normal console pack have all the diagnostics, boot images, microcode,
and so on, there is no other system on that pack.
This means that you are expected to replace the console pack at this
point with another RL02 which contains some kind of a system.
For normal VMS installations, this is how you initially install VMS. The
second RL02 will contain STABACKIT, which is the standalone backup
system. That is in turn used to restore from tapes to some actual other
drive you have on the system, thus creating a bootable system disk.
Unless you really are installing VMS from scratch, this is probably not
something you want to do, or is what you thought you were doing.
You probably want to boot from some actual disk you have, such as an RA
disk attached to the machine. See my other mail about boot command files
for the 86x0 machines.
Oh, and I have never used Quasijaurus, so for that specific topic I
can't offer any help.
So you have a real physical 86x0 machine? Nice! Ping me off list, if you
want to talk some more about it.

But that's neither here nor there at this point. The 8600 doesn't seem
to be able to run any standalone utilities - they all print one
character to the console and then stop. For example, "copy" and "format":
sim> load -o copy 0
sim> run 2
F
sim> load -o format 0
sim> run 2
D
While on any other vax simulator, I get:
sim> load -o copy 0
sim> run 2
From:
sim> load -o format 0
sim> run 2
Disk format/check utility
Enable debugging (0=none, 1=bse, 2=ecc, 3=bse+ecc)?
I haven't done any real testing of the qbus vax sims, I just verified
that they could load and run standalone utilities.

The last character output in a message just prior to executing a
HALT instruction is not surprising since the simulator implements a
delay (as a number of instructions executed) from when the data is
put in the output register prior to generating the completion
interrupt/status. The halt instruction gets executed before the
delay number of instructions have completed. Even if that was
'fixed', nothing operational would change. The reason the message
has been generated will still exist.
As for direct support for booting an OS from the console media, the
8600 supports BOOT CS /R5:xx to boot from the console RL02. Other
than that, VMB.EXE is actually performing the boot operation and I
think that when I checked VMB didn't know how to boot from console
floppies on a 780, but it can boot from the console TU58 on both the
730 and 750 (BOOT TD /R5:xx).

What media have you tested with on the other (qbus) VAX simulators?
