Re: vector projector

Being slightly familiar with projectors, the one thing I can tell you is
that the reason for the liquid (Glycol) on the tube is that they run
extremely bright. I have a feeling that if you were to slow the beam
movement dow for a vector game, it would instantly burn the CRT face. In
fact many of these types of projectors have a scan failure detection that
will kill the beam. On the types that don't have scan failure, you usually
have to replace the burnt tube if the vertical went away even for a second.
Anode voltages run up over 80KV to give you some idea of how bright.
That said, I suppose it would be pretty cool if someone could make it work.
