Editing 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).

== What this document does not contain ==
No architecture beyond the changes and no service information. The earlier models are in [[Power Macintosh 7300, 7600, 8600 and 9600 Computers Developer Note]]; repair procedures are in [[Power Macintosh 8600/ 9600 & WS 9650 Service Source]].
