- 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 :-) !!
