Hardware Interfaces
The Macintosh family of computers supports many different types of
hardware, including mouse devices, keyboards, display devices, hard disks,
floppy disks, CD-ROM discs, and other devices. These devices are supported
through various hardware interfaces, including SCSI (Small Computer System
Interface), ADB (Apple Desktop Bus), and SCC (Serial Communications Chip).
In addition, a number of different devices can be supported through the
expansion interfaces (the NuBus and processor-direct slots).
You can design expansion cards and drivers for the NuBus and
processor-direct slots. For specific hardware information for the Macintosh
family, see the Guide to the Macintosh Family Hardware, second edition. For
information on writing a driver for the Macintosh family, see Designing Cards
and Drivers for the Macintosh Family, second edition.
You will find information here on the new Power Manager and additional used with the Macintosh Por table. The Slot Manager in System 7.0 supports 32-bit addressing of NuBus cards. See the the sections on the
managers.
