Yes ;-))

There is a jumper on the motherboard, to disable ALL graphics,
and switch to the serial console. It's the little switch on the lefts side
of the diagnose LEDs.

If you like to see what's in the monochrome framebuffer, you have to use a
different cable for the video, because the video signal (monochrome) is not
on any of the R-G-B signals, but on a different pin.

Advantage ? you can use two monitors on one Vax.
Disadvantage ? You have to find the right cables ;-))

But the description is somewhere here, but i don't remeber where.

I guess, i make a Video on Vaxstations FAQ ;-))

cheers & have fun,
