I've seen this, when the 20 pin cable
from M7859 to the console panel
is plugged in reversed.
Don't trust the marked pin 1 wire:
sometimes DEC manufacturing twisted
the cables.
hope this helps,

All LEDs "glowing dark"?
And sure enough, I flipped the cable
around and things are much happier,
the front panel is completely
responsive and the CPU and bus seem to
be working but I'll need to spend some
more time with it to test stuff out.
That'll learn me to trust Pin-1
markings on DEC stuff :).
Thanks all for the suggestions, it's
all been very educational...
