Macintosh 630 Family Computers: Apple IIe Card Not Compatible
This article discusses compatibility between the Apple IIe Card for the Macintosh LC and the Macintosh 630 Family computers (Macintosh LC 630, Quadra 630, and Performa 630).
Because the 630 Family computers operate only in 32-bit addressing mode, they do not support the Apple IIe card for the Macintosh LC.
