Apple IIGS Incompatibilities: CP/M Cards The Apple IIGS is designed to be used with the vast majority of Apple IIe hardware and software. However, there are some design differences that will cause some products to be incompatible with the Apple IIGS. Some CP/M cards designed for the Apple IIe use non-Apple conventions on the I/O Select and Device Select lines in the expansion I/O slots. These cards are not compatible with an Apple IIGS. Among others, cards currently available from Microsoft and Digital Research cannot be used on a IIGS. Apple Technical Communications
