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. >5.)

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. >> Can the smallish RGB monitor which came with the //gs >> be used on a Mac? > >Yes, but with such inferior results that you probably shouldn't bother >trying. And only with one particular Mac video card. Most Macs can't generate a video signal that the GS monitor can handle. - Neil Parker -- Neil Parker, nparker@ssil.uoregon.edu, nparker@axis.llx.com, http://axis.llx.com/~nparker/ (Note new addresses and home page!)
