Basics Rev. B, 5000 Series - 2

Rev. B, 5000 Series

Apple introduced an updated 5000 series version several
months after introduction. Referred to in this manual as
“Rev. B,” the updated version incorporates design changes
that are not backward-compatible. Models in the 5500
series are made entirely with Rev. B parts.

To determine which version you are servicing, remove the
front bezel and note the location of the speakers. If the
speakers are part of the front bezel, the unit is the original
version. To service the original version, follow the manual
for take-apart procedures and parts information, unless the
procedures specify Rev. B.

If the speakers are attached to the sides of the metal chassis,
the unit is Rev. B. To service Rev. B models, follow the
manual, substituting Rev. B procedures and parts.

Intelligent Device Electronics (IDE) Hard Drive

The internal hard drive uses Intelligent Device Electronics
(IDE) technology, commonly used in DOS-compatible
systems. The IDE hard drive functions the same as a typical
SCSI hard drive. You must replace IDE drives like-for-like.

The IDE drive does not affect SCSI ID selections or SCSI
termination schemes. Seven external SCSI devices may be
daisy-chained through the external SCSI port.

Basics Video-In Card - 19

Video-In Card

The Video-In Card is an optional card included with the Apple
Video System. It allows users to digitize video from the TV
Tuner and external composite or S-video inputs. It accepts
NTSC, PAL, or SECAM format video and also provides stereo
audio inputs.

Install the Video-In Card into the dedicated 60-pin, 1.75­inch video slot.

Basics TV Tuner Module - 2 0

TV Tuner Module

The TV Tuner, an optional module included with the Apple
TV/Video System, turns the computer into a television
receiver. The TV Tuner requires the Video-In Card, which is
also included with the Apple TV/Video System. The TV Tuner
receives incoming television signals from cable or antenna
television inputs, and then sends the information to the
Video-In Card, which converts the data for display on the
screen. In the United States, only NTSC is supported, but
PAL and SECAM are available internationally.

Install the TV Tuner in a separate bay at the rear of the
computer, below the logic board.

Basics TV Tuner Module - 2 1

TV/FM Radio Tuner Card

The TV/FM radio tuner card turns the computer into a
television and FM radio receiver, complete with remote
control. An expansion ribbon connector for the optional
TV/FM radio tuner card provides NTSC and PAL input from
an external TV antenna or cable. Change channels by typing
the channel number on the keyboard or with the remote
control. Switch between the current and previous channel by
pressing the Tab key. The computer displays the user­assigned channel name on the picture in the video window.

Apple Video Player software supports the TV/FM tuner card.
The user can disable channels and require a password to
access the disabled channels. Users can also capture or
freeze a single frame of video or record a segment of video as
a QuickTime movie. It isn’t possible to resize the window
while recording a movie.

Basics TV Tuner Module - 2 2

The TV picture is in its own window on the desktop, and the
default size of the window is 320x240 pixels. The picture
can be resized from 160x120 pixels up to 640x480 pixels.
The resolution of the picture does not increase at larger
window sizes, but the image is expanded by doubling the
pixel size or by two-dimensional linear interpolation.

The TV signal is carried in YUV format for improved picture
clarity. The YUV format is 16-bit, with 8 bits for the Y
(luminance) channel and 8 bits for the U and V
(chrominance) channels to share by multiplexing. The
picture is clearer because the YUV format carries more
levels of luminance information.

Basics TV Tuner Module - 2 3

The card is available in versions for NTSC, PAL, and SECAM
television systems. The features of the TV tuner include the
following:

• Remote tuner for 181 broadcast and cable channels (U.S.
version)

• Coaxial connector for TV antenna or cable input (F-type
connector in U.S. and Japanese version, IEC-type
connector in Europe)

• TV picture in a resizable and movable window

• YUV format for improved clarity

• Closed captioning and teletext support

• Software password protection

• Automatic and manual channel programming

• Single remote control for TV and for playback of audio
CDs

Basics TV Tuner Module - 2 4

The features of the FM radio tuner include the following:

• FM radio frequencies received and displayed

• Stations scanned and searched up and down the frequency
spectrum

• Step frequency

• DX mode to tune out harmonic spillover from other
stations

• Stereo/mono station indicator

• Preset station programming

Basics Digital Audio Video (DAV) Technology - 25

Digital Audio Video (DAV) Technology

The optional video input card has a separate connector called
the DAV connector. The DAV connector provides access from a
PCI card to the video input card by means of a 60-pin cable.
This allows the PCI expansion card to use the video card to
transfer real-time video data to the computer. The video
card accepts video from an external source and displays it in
a window on the computer’s monitor.

Note:

The interface of the 60-pin DAV connector is a
superset of the interface on the 34-pin DVA connector on the
Power Macintosh 5200, Power Macintosh 6200, and Quadra
630 computers. An adapter cable is provided with the
Performa 6400 video-in cards to connect 34-pin DVA
compatible cards developed for the Power Macintosh 5200
and 6200 computers to the new 60-pin DAV connector.

Basics External Video Connector - 27

External Video Connector

The External Video Connector is an optional module that
provides the computer with video output (mirroring).
Install the External Video Connector in a dedicated 3/4­inch, 22-pin slot on the logic board.

Basics Apple Presentation System - 28

Apple Presentation System

The Apple Presentation System (APS) is an external module
that uses the 15-pin video output connector on the
computer, and then provides a video signal for a separate
television display or for recording on a VCR. The APS
supports video mirror mode, where the image on the
television display is the same as the computer’s primary
video monitor. The APS is required for video mirroring.

Basics Peripheral Component Interconnect (PCI) - 2 9

Peripheral Component Interconnect (PCI)

The 5400 and 5500 series 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 GeoPort Technology - 3 0

GeoPort Technology

GeoPort is a hardware and software communications
architecture that has been optimized for computer­telephony integration. It has the following attributes:

• It allows you to connect any GeoPort-compatible
computer 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 Technology - 3 1

• 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 The Cuda Chip - 32

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. Press the Cuda reset button on the logic board to reset
the Cuda chip. See the logic board diagram later in this
chapter to locate the Cuda reset button.

Basics Dual In-Line Memory Modules (DIMMs) - 33

Dual In-Line Memory Modules (DIMMs)

The 5400 series and 5500 use DRAM Dual In-Line Memory
Modules (DIMMs) instead of DRAM Single In-Line Memory
Modules (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.

Important:

Basics Dual In-Line Memory Modules (DIMMs) - 34

Power Macintosh/Performa 5400 Series

DRAM DIMMs can be installed individually. However, to take
advantage of the computer’s interleaving capability (which
provides maximum performance), you must install the
DIMMs in matching pairs. Memory interleaving allows the
computer to read or write to its memory while other
memory reads or writes are occurring, providing faster
performance.

Note:

DIMMs purchased from different manufacturers can

be paired as long as they are the same size and speed.

Basics Dual In-Line Memory Modules (DIMMs) - 35

Power Macintosh/Performa 5500 Series

DIMM slots on the 5500 logic board accommodate 168-pin
5-volt EDO DRAM DIMMs. However, 3.3-volt EDO DIMM
cards are not supported and will not mechanically fit into
the DIMM connectors on the logic board.

The 8-byte DIMMs can be installed one or more at a time.
The 5500 logic board supports only linear memory
organization, and no performance gains result when two
DIMMs of the same size are installed. Any supported size
DIMM can be installed in either DIMM slot, and the combined
memory of all the DIMMs installed will be configured as a
contiguous array of memory. The largest DIMM supported is
a two-bank DIMM holding 64 MB.

Troubleshooting General - 1

General

The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because
cures are listed on the charts in the order of most likely solution,
try the first cure first. Verify whether the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(

Note:

If you have replaced a module, reinstall the original module

before you proceed to the next cure.)
If you are not sure what the problem is, or if the Symptom Charts

do not resolve the problem, refer to the Flowchart for the product
family.

For additional assistance, contact Apple Technical Support.

Troubleshooting First Checklist - 2

First Checklist

Jitter, faint lines, or screen movement can be caused by external
interference such as electronic devices and fluorescent lights.
Move the unit to another room or building to help determine if
external interference is the source of the problem.

A misadjusted screen can mimic the same symptoms as analog
board or CRT failures. By performing the adjustment procedures,
you might determine if one or more of the adjustments is the
cause of the problem.
