OK.  If you installed the Supervisor Series sources, you can modify
SUPERVISOR.MAR to produce the desired results.  I want to mention again
that the consoles are *supposed* to hang when advised, so use this patch
with caution unless you're Shawn.  Meanwhile, I'll find out what I can
about whether or not the 62xx is really different from the others.

If you didn't install the sources, you can re-install the Supervisor
Series, or you can just restore the saveset SUPSER052.C:

        $ BACKUP/LOG SUPSER052.C/SAVE SUPSER_ROOT:[SRC]

You can then EDIT SUPERVISOR.MAR, find the label U.19:, then search for
the label 40$, which looks like this:

40$:    CMPL    16(SP), #10
        BNEQ    41$
        CMPL    20(SP), #2

Just add the following BRB instruction at 40$:

40$:    BRB     45$             ;Patch to skip console checks
        CMPL    16(SP), #10
        BNEQ    41$
        CMPL    20(SP), #2

Or you can comment out the instructions between 40$ and 45$. The
instruction at 45$ looks like this:

45$:    BICB2   #1, L^U.27
46$:    BBC     #4, L^U.27, 47$

Making that change will cause SUPERVISOR to skip all the console checks.

To rebuild SUPERVISOR.EXE, you're in luck if you have MMS:

        $ MMS SUPERVISOR.EXE

If you don't have MMS, you'll have to look at DESCRIP.MMS for the section
that builds SUPERVISOR.EXE.  You should be able to figure out from that
which modules must be assembled and linked.

Once you have the new SUPERVISOR.EXE, just copy it to SUPSER_ROOT:[EXE] and
execute SUPSER_ROOT:[COM]SUPSER_STARTUP.COM to install that version.
