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 9500/200.

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

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.

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.

 

 

 

 

 

 

 

 

 

 

Basics The Cuda Chip - 16

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 red 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.

Resetting the Logic Board - 17

 

 

 

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.

1Unplug the computer.

2Remove the logic board. (Refer to the Take Apart chapter for instructions on how to remove the logic board.)

3Using a small flat-blade screwdriver, pry open the latch at the end of the battery holder and lift off the battery holder cover.

4Remove the battery from its holder.

Basics

Resetting the Logic Board - 18

 

 

 

 

5 Verify the power supply cable is disconnected 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.)

 

6 Wait at least 10 minutes before replacing the battery.

 

Make sure the battery is installed in the correct +/-

 

direction.

 

7 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.

Fast SCSI - 19

 

 

 

Fast SCSI

The Power Macintosh 9500 Series computers offer Fast SCSI support on the internal SCSI connector, which provides for significantly enhanced data throughput. The internal SCSI bus on these computers supports transfer rates up to 10 MB/sec.
