Enhanced Power Macintosh 8600 and 9600 Computers Developer Note

Enhanced Power Macintosh 8600 and 9600 Computers is Apple Computer's developer note dated 7/9/97 (Apple Technical Publications, © Apple Computer, Inc. 1997), 22 PDF pages. It is a delta guide to the Power Macintosh 8600/250, 8600/300, Power Macintosh 9600/300 and 9600/350, which use the Mach 5 PowerPC 604e on a new processor card with 1 MB of Apple inline cache.

Contents

With printed page numbers, all in Chapter 1, Delta Guide to the New Models:

• New models (p. 2), Table 1-1
• New features (p. 2): new processor card, Mach 5 microprocessor, clock speeds (3), Apple inline cache, 4 GB hard disk, 24× CD-ROM, built-in Zip drive, accelerated display card (6)
• Configurations (p. 7)
• System software (p. 8): ROM and disk software changes, Mac OS 8 availability
• Compatibility issues (p. 8): machine identification, system software, RAM DIMM specifications, corrected sense code table (9)

What it settles

• The new processor card will not work in an older 8600 or 9600 logic board, because the control logic on the board was changed (p. 3).
• Cache bus 100 MHz, system bus 50 MHz (pp. 2–3).
• DIMMs are 168-pin, 5 V, 64-bit; both the earlier and the 250 to 350 MHz 8600 and 9600 take DIMMs 1.1 or 1.255 inches tall (p. 9).
