Ya know what,
 My boss presented me with the same problem!! We have a Sayett graphics
projector that she wants to pump video thru now!! Sayett want $1000 (!!)
for a 'Universal Video Decoder' I think Motorola makes a video->RGB
convertor chip, so I'm going there after work, and I'll let you know what I
find. My question to you is: Is sync on a separate pin on VGA connector,
does anybody know where sync is on Macintosh video connectors? I've heard
it can be composited with the Green signal. If so, I'll need that sync
separator circuit :-) !!
