Does anyone know the exact details of analog RGB? Specifically, can
I use my Apple IIgs RGB monitor on an IBM VGA analog card (with the
appropriate cables...) I have a friend who owns both an IBM and a MAC
with monitors that are interchangable, this is what lead me to believe
it might be possible.

Well, you'll have to make an adapter cable, and the GS monitor will only be able to display CGA graphics modes, but it's probably possible. Your friend's monitor is probably a multisync/multifrequency monitor, and is more intelligent (& more expensive) than the GS monitor. Todd Whitesel toddpw @ tybalt.caltech.edu

I'd be hesitant to make such an adapter cable. The CGA emulation in VGA boards actually has the scan rates of 640x400 noninterlaced video, with pixels doubled horizontally and vertically. Plus, there's always the possibility of running a program that autodetects your video board and drops it into a higher resolution mode. I'm not sure if it is possible to destroy or damage a monitor by giving it signals that are not within its specs. I've seen monitors shut off and go crazy...is there any possibility of lasting damage? -- Dave Seah | Omnidyne Systems-M | INET: seah@ee.rochester.edu ^..^ | "User-Friendly Killing Machines" | America Online: AFC DaveS yargh! +----------------------------------------------------------------=*
