Basics PowerPC 604e Microprocessor - 12
PowerPC 604e Microprocessor
The Power Macintosh 8600 and 9600 Series and Workgroup
Server 9650 computers feature the PowerPC 604e RISC
microprocessor. The PowerPC 604e microprocessor is
installed via a card that plugs into the logic board, allowing
for maximum flexibility with future upgrades.
Features of the microprocessor include
• Full RISC processing architecture
• Parallel processing units: one load-store unit, two
integer units, one complex integer unit, and one floating
point unit
• Separate built-in 32K caches for data and instructions
• Advanced branching techniques for improved throughput
• Bus multiplier up to 7:1 with Mach V
Basics Peripheral Component Interconnect (PCI) - 13
Peripheral Component Interconnect (PCI)
The Power Macintosh 8600 and 9600 Series and Workgroup
Server 9650 computers offer a Peripheral Component
Interconnect (PCI) expansion bus. Because the PCI bus is an
industry standard, most existing PCI 2.0-compliant cards
(with the addition of a Mac OS-specific software driver)
will work in these computers.
PCI offers significantly higher performance than the NuBus
architecture used in previous Macintosh models. Running at
33 MHz, the PCI bus is up to three times faster than NuBus,
offering overall enhanced system performance, particularly
in the areas of video and networking.
Basics Dual In-Line Memory Modules (DIMMs) - 14
Dual In-Line Memory Modules (DIMMs)
The computers in this manual ship with extended data output
(EDO) DRAM dual in-line memory modules (DIMMs)
instead of DRAM SIMMs. Whereas SIMMs have 72 pins,
DIMMs have 168 pins. The extra pins provide a 64-bit data
path, compared to a 32-bit data path for SIMMs. In addition,
DIMMs do not have to be installed in pairs like the SIMMs on
earlier Macintosh models. (However, to take advantage of
memory inter-leaving, the DIMMs should be installed in
paired slots. See “Memory Configurations” in Basics for
more information.)
Important:
only. Single In-Line Memory Modules (SIMMs) used in
previous Macintosh models are NOT compatible with these
computers.

While the Power Macintosh 8600 and 9600 Series
Basics Memory Configurations - 16
Memory Configurations
The Power Macintosh 8600 logic board has eight DRAM
DIMM slots, each with a 64-bit data bus. You can increase
the computers’ DRAM to a total of 512 MB using 5-volt,
64-bit-wide, 168-pin, extended data output (EDO) or
fast-paged mode (FPM), 70 ns DIMMs.
The Power Macintosh 9600 and Workgroup Server 9650
logic board has 12 DRAM DIMM slots, each with a 64-bit
data bus. You can increase the computers’ DRAM to a total of
768 MB using 5-volt, 64-bit-wide, 168-pin, EDO or
FPM, 70 ns DIMMs.
Note:
These computers do not have any main memory
soldered to the logic board. At least one RAM DIMM must be
present for the computers to operate.
DRAM DIMMs can be installed individually; however, if you
Basics Memory Configurations - 17
wish to take advantage of the computer’s interleaving
capability, which provides maximum performance, you
must install the DIMMs in matching pairs and in paired
slots.
Note:
Memory interleaving allows the computer to read or
write to its memory while other memory reads or writes
are occurring, thus providing for faster performance.
For a pair of DIMMs to function as a single 128-bit wide
pair, they must be the same type and size.
Note:
DIMMs purchased from different manufacturers can
be paired as long as they are the same size and speed;
however, they may not interleave.

DRAM slots are located on the PM 8600 and PM 9600/WS
9650 logic boards and how they are numbered.

Basics Ethernet Support - 20
Ethernet Support
There are two Ethernet ports on the PM 8600 and PM
9600/WS 9650 logic boards: an AAUI port and a 10BASE-T
port. You can use only one Ethernet port at one time,
however. If you have cables plugged into both Ethernet
ports, the computer uses the 10BASE-T port by default.
AV Support
The Power Macintosh 8600 comes standard with an AV
module that provides support for: composite video input and
output, S-video input and output, audio input (left and
right), and audio output (left and right).
Basics GeoPort - 21
GeoPort
Geoport is a hardware and software communications
architecture that has been optimized for computertelephony integration. It has three main attributes:
• It lets any computer connect to any telephone (analog or
digital, public or private) anywhere in the world.
• Once connected, it supports an arbitrary number of
independent data streams up to a total bandwidth of
2 MB/second.
• Unlike traditional asynchronous data communications
(such as AppleTalk), GeoPort also supports isochronous
data streams (such as real-time voice and video) and
provides the real-time Application Program Interfaces
(APIs) necessary to hide the implementation details
from both the recipient and the sender.
Basics PC Compatibility Cards - 22
By attaching an Apple GeoPort Telecom Adapter to these
computers, you can enjoy all the features of a 33.6 modem,
including data, fax, send and receive, and voice capabilities.
The GeoPort Telecom Adapter serves as a line interface to
standard (analog) telephone lines. The adapter is capable of
sending or receiving data at up to 33.6 kbps and faxes at up
to 14.4 kbps using the GeoPort Telecom Adapter software.
PC Compatibility Cards
Apple computer offers PC Compatibility Card upgrade kits
that bring full DOS functionality to the Power Macintosh
8600 and 9600 Series computers. The cards plug into any
available PCI slot on the logic board. Refer to the Upgrades
chapter in this manual for installation instructions.
Basics The Cuda Chip - 23
The Cuda Chip
The Cuda is a microcontroller chip. Its function is to
• Turn system power on and off
• Manage system resets from various commands
• Maintain parameter RAM (PRAM)
• Manage the Apple Desktop Bus (ADB)
• Manage the real-time clock
Many system problems can be resolved by resetting the Cuda
chip (see Symptom Charts for examples). Press the Cuda
reset button on the logic board to reset the Cuda chip. (See
“Logic Board Diagram” later in this chapter to locate the
Cuda reset button.) If you continue to experience system
problems, refer to “Resetting the Logic Board” in this
Basics chapter.
Basics Resetting the Logic Board - 24
Resetting the Logic Board
Resetting the logic board can resolve many system problems
(refer to “Symptom Charts” for examples). Whenever you
have a unit that fails to power up, you should follow this
procedure before replacing any modules.
1 Unplug the computer.
2 Remove the battery from the logic board.
3 Disconnect the power supply cable from the logic board
and then press the Power On button. (See “Logic Board
Diagram” later in this chapter to locate the Power On
button.)
4 Wait at least 10 minutes before replacing the battery.
Basics Resetting the Logic Board - 25
5 Make sure the battery is installed in the correct +/-
direction.
6 Reassemble the computer and test the unit.
Note:
This procedure resets the computer’s PRAM. Be sure
to check the computer’s time/date and other system
parameter settings afterwards.
Note:
If this procedure resolves the problem, claim an
adjustment on an SRO. If not, replace the defective
component and DO NOT claim the adjustment procedure.
Basics Fast SCSI - 26
Fast SCSI
The Power Macintosh 8600, 9600, and WS 9650 offer Fast
SCSI support on the internal 50-pin SCSI-2 connector,
which provides for significantly enhanced data throughput.
The internal SCSI bus on these computers supports transfer
rates up to 10 MB/sec.
Only one internal terminator is allowed on the Fast SCSI bus.
In the PM 8600 and 9600, the rear hard drive (the last
device in the chain on the Fast SCSI-2 bus) is terminated.
None of the other devices on this bus should be terminated.
In the WS 9650, however, the unit ships with only
unterminated devices attached to the Fast SCSI bus (that is,
the CD-ROM drive and the optional tape drive). Therefore,
there is a 50-pin terminator attached to the end of the SCSI
cable.
Basics Ultra Wide SCSI - 27
If you are connecting an additional unterminated device to
the Fast SCSI-2 bus in a WS 9650, leave the termination
block attached to the end of the SCSI ribbon cable. If the
device you want to connect is terminated, remove the
termination block and attach the device to the end of the SCSI
ribbon cable.
Ultra Wide SCSI
The Workgroup Server 9650/233 and 9650/350 ship
with a PCI Ultra SCSI JackHammer•SE card pre-installed.
This card is a high performance, single-ended, accelerated
PCI to SCSI host adapter card that dramatically increases
performance of SCSI devices connected to it.
The JackHammer•SE card is a PCI device that creates a
high-speed interface between the CPU and disk drive. The
Basics Ultra Wide SCSI - 28
JackHammer can transfer data through the Ultra SCSI-3
portion of the card at rates up to 40 MB/s (as allowed by the
SCSI-3 specification). The PCI portion of the card is capable
of data transfer rate bursts up to 132 MB/s. This capability
means the Workgroup Server 9650/233 and 9650/350
can receive data as fast as the drives can provide it. Simply
connecting the JackHammer•SE card to the SCSI drives
improves their overall performance.
To ensure the best possible disk I/O performance, the WS
9650 ships with all internal hard drives attached to the
JackHammer•SE card via the 68-pin Ultra Wide SCSI cable.
The WS 9650 allows for a total of four internal Ultra
devices. Due to electrical signal limitations with Ultra
devices, Apple Computer does not recommend connecting
external devices to the JackHammer•SE card.
Some of the drives that are installed in the WS 9650 at the
