Hi Henry.

We use Barco projectors, which are nice (but expensive). The problem is that
the Symbolics monitors use phase-encoded video, which is hard to decode.
When we attached our monochrome monitors, we had to open up the back of
the monitor and grab the signal *after* it was decoded. My guess is that
you would have to do that for any projector you get. [Anyone know for
sure?] We just leave this connector permanently inside our monitor, even
when the projector is not being used.

Color is no problem, since the standard RGB connectors are used, as you
probably know.
