I've just got hold of an old (probably late-80s) Hughes 800 projector.
It's a couple of feet long and very very heavy. Inside is a big xenon
lamp, a CRT of some kind, and some optics. It appears to work by
shining the lamp (through mirrors) onto the face of the CRT. The big
problem is, it doesn't appear to produce any video. I can hear the CRT
scan coils going. The scan pitch changes when I remove the video
source. In fact, it does appear to do all the things I'd expect when I
press buttons, but no picture comes out :-/
There is (getting vaguely on-topic) an RS-232 port and it appears to use
a TMS9900 CPU inside.
Anybody got any idea how it even works? Even better, has anyone got an
idea how to make it work *properly*?
Gordon.
