It's in the Pro 300 technical manual, on Al's website.

The video connector is a bit weird. It carries both a mono
(grayscale) signal with standard sync, and also on separate wires an
RGB signal with sync on blue (not on green). Don't know if the
Rainbow and DECmate have a color option, but the Pro does and that's
where it goes.

And yes, the whole thing is powered, rather poorly, from 12 volts.
(Poorly: if you flip significant quantities of white pixels on and
off, the scan area expands and shrinks very noticeably. So clearly
the supply regulation is seriously inadequate.)
