K Service Source Basics Power Macintosh 9500 Series
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.
Basics Overview - 2 Features of the Power Macintosh 9500 Series include • 120, 132, 150, 180 (multi-processor) or 200 MHz PowerPC 604 microprocessor card with built-in FPU • Six PCI expansion slots • 10 MB per second internal SCSI channel, 5 MB per second external SCSI channel • 512K Level 2 cache • DRAM expansion up to 1536 MB using 168-pin, 70 ns, 64-bit DIMMs • A PCI Apple Accelerated Graphics card included with some configurations (the Power Macintosh 9500 Series does not include on-board video suppor

Basics 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.
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.
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.
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.
Basics Memory Configurations - 11 write to its memory while other memory reads or writes are occurring, thus providing for faster performance. The graphic on the following page illustrates the memory locations on the Power Macintosh 9500 logic board.

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.
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.
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.
Basics 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. 1 Unplug the computer. 3 Using a small flat-blade screwdriver, pry open the latch at the end of the battery holder and lift off the battery holder cover. 2 4 Remove the logic board.
Basics Resetting the Logic Board - 18 5 6 7 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.) Wait at least 10 minutes before replacing the battery. Make sure the battery is installed in the correct +/direction. Reassemble the computer and test the unit. Note: This procedure resets the computer’s PRAM.
Basics 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.
Basics Rear View Diagram - 20 Rear View Diagram The Power Macintosh 9500 Series computers offer the following external ports: SCSI, AAUI Ethernet, 10BASE-T Ethernet, serial printer (GeoPort compatible), serial modem (GeoPort compatible), ADB, sound input, and sound output. Some configurations of the Power Macintosh 9500 also includes a DB-15 video port on the Apple Accelerated Graphics card, which installs in one of the PCI slots on the logic board.
