With the switch down (the normal position)
the console is on MMJ-0 and a <BREAK>
on the terminal will be ignored. With the
switch up MMJ-3 will be used as the
alternative console and <BREAK> will
halt the system.

As far as autobooting goes, that's
not dependent on the switch setting - it
depends on the console settings as
stored in NVRAM.

I think this is pretty much the same
for all the MicroVAX 3100 systems.
It is also true for all the VAXstation
3100/4000 systems except (as you note)
with the switch down the graphics
head is used as a console and
not MMJ-0.
