Basics
Overview - 1
Overview
The Power Macintosh 9500 Series computers are based on
the PowerPC 604 microprocessor and support the
industry-standard PCI (Peripheral Component
Interconnect) bus specification. These computers are the
most flexible, expandable, and highest-performance
systems from Apple to date.
The microprocessor for the Power Macintosh 9500 Series
computers is on separate plug-in card, which allows for
easy upgrades. The Power Macintosh 9500 family includes
five versions: the 9500/120, the 9500/132, the
9500/150, the 9500/180MP (multi-processor), and the

PowerPC 604 Microprocessor - 5
PowerPC 604 Microprocessor
The Power Macintosh 9500 Series computers feature the
highest performance PowerPC processor available: the
PowerPC 604 RISC microprocessor. Designed to bring
unprecedented levels of performance to desktop computers,
the Power PC 604 processor offers up to 1.5 times the
performance of the PowerPC 601 processor at the same
clock speed. Features 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 caches for data and instructions, 16
KB each, four-way set associative
• Advanced branching techniques for improved throughput
Basics
Multi-Processor Support - 6
The PowerPC 604 processor is installed via a processor
card that plugs into the Macintosh 9500 Series logic board,
allowing for maximum flexibility with future upgrades.
Multi-Processor Support
The Power Macintosh 9500/180MP features two 180 MHz
PowerPC 604e chips on its microprocessor card. This
computer provides extremely rapid performance for
applications that can take advantage of its coprocessing
capabilities.
Basics
Peripheral Component Interconnect (PCI) - 7
Peripheral Component Interconnect
(PCI)
The Power Macintosh 9500 Series 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 OSspecific software driver) will work in the Power Macintosh
9500 Series 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) - 8
Dual In-Line Memory Modules
(DIMMs)
The Power Macintosh 9500 Series computers use 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
interleaving, the DIMMs should be installed in paired slots.
See "Memory Configurations" in Basics for more
information.)
Important: The Single In-Line Memory Modules (SIMMs)
used in previous Macintosh models are NOT compatible with
Basics
Dual In-Line Memory Modules (DIMMs) - 9
the Power Macintosh 9500 Series computers.
Note: There is a double click seating process for installing
DRAM DIMMs. Be sure to push the DIMMs all the way into
the DIMM slots.
Basics
Memory Configurations - 10
Memory Configurations
The Power Macintosh 9500 Series logic board has 12 DRAM
DIMM slots, each with a 64-bit data bus. You can increase
the computer’s DRAM to a total of 1536 MB using 5-volt,
64-bit-wide, 168-pin fast-paged mode, 70 ns DIMMs.
When installing DRAM DIMMs in the Power Macintosh
9500, fill slot A6 first, followed by B6, then A5, followed
by B5, and so on. DRAM DIMMs can be installed individually;
however, to take advantage of memory interleaving, which
provides maximum performance, you must install the
DIMMs in matching pairs and in paired slots (A6 and B6
first, then A5 and B5, and so on). DIMMs purchased from
different manufacturers can be paired as long as they are the
same size and speed.
Note: Memory interleaving allows the computer to read or

are occurring, thus providing for faster performance.

Basics
Ethernet Support - 13
Ethernet Support
There are two Ethernet ports on the Power Macintosh 9500
Series logic board: 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.
PC Compatibility Cards
Apple computer offers two PC Compatibility Card upgrade
kits that bring full DOS functionality to the Macintosh
computer. Two versions of the PC Compatibility card are
available: a 7" card and a 12" card. The cards plug into any
available PCI slot on the logic board. Refer to the Upgrades
chapter in this manual for installation instructions.
Basics
GeoPort - 14
GeoPort
Geoport is a hardware and software communications architecture that has been optimized for computer-telephony
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
GeoPort - 15
By attaching an Apple GeoPort Telecom Adapter to the Power
Macintosh 9500, you can enjoy all the features of a 14.4
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 14.4 kbps and
faxes at up to 9600 bps using the GeoPort Telecom Adapter
software.
