I took the easy (and less expensive) way out and bought an
Apple monitor //e (40 column color and 80 column, hi-res
monochrome) partly because Apple and RGB got too puzzling.

IBM-PC RGB monitors evidently don't use the same signals as
Apple RGB boards generate.  Video-7 makes a board (add-on
device) that changes Apple RGB output to IBM monitor compatible.

I've seen some monitors that advertise a switch or other internal
(maybe special cable) for either Apple or IBM.

A friend of mine got a nice deal on an Apple 80 column card with
an RGB plug that turned out not to be compatible with anything
except the (very expensive) Apple brand RGB monitor.  Video-7
did have a Mappler for it however (must be like the //c's RGB
output which doesn't seem to just plug into a monitor but needs
something -- a Mappler //c? -- added in order to work).

The long and the short of it is ask a lot of questions about just
which RGB monitors you can plug into the chip for the AE card.
The IIgs's analog RGB monitor definately won't work.
