A hawk indeed.

Even if it was an old projector it'd at least have a standard 'video in' job (little yellow av plug) hehee.

Then it might have s-video, and probably vga.

If it's a really good one it might even have DVI.

I say this guy's a pathetic idiot for a 'bigtime computer guy', especially if he thought a projector would use a SERIAL port.
