The Monitor /// is compatible with every Apple II model. Just plug it into
the RCA video jack. There are at least two varieties of Monitor ///--a
black-and-white model, and a green screen model.

Actually, you CAN run DOS 3.2 and earlier on a IIc or IIGS. But unless you
have an old 13-sector disk interface card, you'll need a special pre-boot
program to boot a DOS 3.2 disk. The DOS 3.3 system master disk includes a
program called "BOOT13" that does the trick, and way back in the Olden Days
Apple distributed a disk called "BASICS" that also did it.

True, you don't hear much about CP/M these days, but back in its heyday,
there were several different CP/M cards for the Apple II. Unfortunately,
each brand requires its own special boot disk, which isn't compatible with
any other CP/M card. (At least their data disks are interchangeable.)
I have Microsoft CP/M card in my IIGS. I don't use it very often, but
sometimes it's fun to play with.

And only with one particular Mac video card. Most Macs can't generate a
video signal that the GS monitor can handle.
