Power Macintosh 7200 Computer Developer Note

Power Macintosh 7200 Computer is Apple Computer's developer note (Developer Press, © Apple Computer, Inc. 1995), 90 PDF pages, an electronic original with a text layer. It is written for hardware and software developers and describes the Power Macintosh 7200: the PowerPC 601 processor, the Platinum memory and video controller, Bandit PCI bridge and Grand Central I/O, the I/O ports, the DIMM and cache slots, three PCI slots and the system software of the time.

Contents

With printed page numbers:

• Chapter 1, Introduction (p. 1): appearance and features (2), comparison with other Power Macintosh computers (5), configurations and options (7), compatibility (8), power supply (9)

• Chapter 3, I/O Features (p. 19): serial, ADB, Ethernet, SCSI, sound and monitor connectors (20–27); floppy, hard disk and CD-ROM drives (28–29)
• Chapter 4, Expansion Features (p. 31): RAM DIMMs and their connectors, address multiplexing, refresh and dimensions (32–38); second-level cache SIMM (40); PCI expansion slots (42)
• Chapter 5, Software Features (p. 45): large partition support, Open Transport, Open Firmware startup, Energy Saver, PCI and native driver support
• Chapter 6, Large Volume Support (p. 59)
• Glossary (p. 69); Index (p. 73)

What it settles

• The power supply is not self-configuring: it has a two-position voltage switch, set at the factory for the region of sale, which must be changed if the computer moves to a region with a different mains voltage (p. 9). Apple's Service Source calls the supply automatically configured; Power Macintosh 7200 gives both.

What this document does not contain

Written for developers: no service procedures, schematics or component values. Repair procedures are in Power Macintosh 7200 Series/WS 7250 Service Source; the logic board drawing is Power Macintosh 7200 Logic Board Schematic. The later 7200/100 and 7200/120 are covered by Improved Power Macintosh Computers Developer Note.
