From http://til.info.apple.com/tilarchive.nsf/artnum/n8458: The Apple IIe card is only compatible with computers that have the LC style processor direct slot (PDS) and do not require 32-bit addressing. This includes: * Macintosh Color Classic * Performa 400 series * Macintosh LC/Performa 500 series computers (except the Macintosh LC 580 and Performa 580) * Macintosh LC series computers except: Macintosh 630 family, Power Macintosh 5200 and 5300 LC, Macintosh Performa 5200, 5300, 6200, 6300 series. The Macintosh LC 580, Macintosh 630 Family, Power Macintosh 5200 and 5300 LC, Performa 5200/5300 and 6200/6300 series only operate in 32-bit addressing mode. Since the Apple IIe card is not compatible with 32-bit addressing, the Apple IIe Card is not compatible with these computers. The Power Macintosh 5400 and 6400 series and the Macintosh Performa 6400 series and 6360/160 computers do not have LC-PDS slots. These computers have PCI expansion slots. Thus, they do not support the Apple IIe card. -- Paul R.
