The AppleColor High Resolution Display is a Mac monitor. Designed only for the Mac. So long as you have the correct DB-15 to DB-15 cable, it will plug straight into any LC.
The AppleColor RGB Monitor, on the other hand, is a IIGS monitor. As far as I'm aware this monitor was never marketed as a Mac monitor, and is not electrically compatible with the Mac's video output. Furthermore, even if it was the resolution would be way too low to use on a Mac.
