Use 27' iMac as monitor

I will shortly be replacing my "mirror-door" dual-boot G4 with a new 27-inch iMac. I've always used the G4 with the Apple 20-inch cinema display (it works perfectly well with both OS9 and OS X despite anything you've read to the contrary). I have a couple of programs which will only run in OS9 (must be native, not Classic) so I will keep the G4 for this purpose, but I don't have room for two displays. OK, here's the question - is there any way that the new 27-inch iMac can act as a monitor for the G4 running OS9 for the few occasions I will still need OS9? I know it can be used as a remote monitor for OS X using special adaptor cables...but OS9? Any information appreciated. Thanks

Hello, thanks for your response. However, what I was asking was the reverse of what is featured in the link - I wish to use the 27" iMac as a monitor for an older computer, not to use an older computer as a second monitor for the iMac. Also, when I said "new iMac" it was maybe misleading - I'm intending to find one of the late 2009 / 2010 models which, according to various discussions, has video-in capabilities. My G4 has DVI and VGA outs, so it would need to from one of these to the MiniDisplay in, if I've got that right? Thanks

We covered that in that discussion too.

Just thought I'd re-use the answers. From what I've seen, it is possible with VNC to get at the headless computer. So primary or second, same ideas, same apps.
