Power Macintosh/Performa 5200

and 5300 (not 5260, 5280)

Basics System Overview - 1

System Overview

The Power Macintosh 5200/5300 computer series
combines RISC-based PowerPC performance, full
multimedia features, and low cost in a sleek all-in-one
design.

The design includes expansion slots for 68040 LC
communications and PDS cards, as well as other video-in,
video tuner, and video-out options. Options include an IDE
hard drive in a variety of capacities and a trayloading CD­ROM drive.

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.

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.

Basics Rev. B, 5000 Series - 3

Another way to identify a 5200 series version A and Rev. B
is to look at the back of the computer for the part number
and manufacture date. The label with this information is on
the lower part of the plastic case. Version A contains one of
these numbers: 620-0635 or 620-0835. Rev. B contains
one of these numbers: 620-0637 or 620-0837.

Basics Performa 5320CD - 4

Performa 5320CD

The Performa 5320CD supersedes the 5300CD. It has a
PowerPC 603e processor running at 120 MHz and 16 MB of
RAM on the logic board. All other hardware features are the
same as the Performa 5300CD. This is an international
product not sold in the U.S.

Basics Open Transport - 5

Open Transport

Open Transport 1.1 does not work on 5200 or 5300 Series
computers. These computers require Open Transport 1.1.1.
When version 1.1.1 is installed on these computers, a dialog
box may appear indicating that a hardware issue was
detected. This message means that Open Transport can’t be
installed until the cache/ROM DIMM is replaced.

The required repairs are covered under the Apple Repair
Extension Program. The models included in this program are
Power Macintosh 5200/75 LC and 5300/100 LC,
Macintosh Performa 5200, 5215, and 5300. Look for
repair program instructions in the REA Procedures chapter.

Basics Service Strategy - 6

Basics Service Strategy - 8

Diagnostics

Use MacTest Pro for Power Macintosh to perform
diagnostics on the Power Macintosh/Performa 5000 series.

Design for Serviceability

To access the floppy drive, CD-ROM drive, or front panel
control board, remove the drive and controls bezel. To
service the logic board, hard drive, or video options, remove
the I/O door. The logic board slides out from a connector
similar to the connector on Macintosh LC 630 and LC 500.

The CRT and degauss frame are matched at the factory and are
removed and replaced as a unit. The chassis harness is one
service module, including the metal chassis and logic board
connector with cables.

Basics User Controls - 9

User Controls

User controls include

• Soft power-on control from keyboard

• Front-panel sound-control pushbuttons

• Front-panel brightness-control pushbuttons

• Optional infrared remote control

Basics Internal Expansion Connections - 10

Internal Expansion Connections

Expansion connections on the logic board include

• 2 DRAM SIMM expansion slots

• LC Processor Direct Slot (PDS)

• Communications slot for modems and Ethernet

• Video-in slot for real-time video display, capture, and
overlay

• External video port

An expansion ribbon connector for an optional TV Tuner card
provides NTSC and PAL input from an external TV antenna or
cable.

Basics Intelligent Device Electronics (IDE) Hard Drive - 11

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 Processor Direct Slot (PDS) - 12

Processor Direct Slot (PDS)

The LC-PDS is compatible with the PDS in the Macintosh LC
family of computers, but it is not a true PDS. Like the
expansion slot in the other models in the Power Macintosh
and Performa 5000 series, this expansion slot supports
many PDS cards designed to operate with the MC68030 bus.

While the I/O expansion slot accepts PDS cards designed for
the Macintosh LC family of computers, some of those cards
do not work. PDS cards designed to interact with the main
processor—to provide, for example, a RAM cache or an
FPU—will not work in the I/O expansion slot.

Basics Video-In Card - 13

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, MPEG Card, 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 MPEG Card - 14

MPEG Card

The MPEG Card is an optional card included with the Apple
MPEG Media System. The MPEG Card requires that the
Video-In Card be installed. It provides hardware
decompression for MPEG movie files, enabling full-screen
(through pixel doubling), 30-frames-per-second, 24-bit
video playback with 16-bit audio. After the MPEG movies
are compressed, they are sent to the Video-In Card, which
converts the data into digital format for output to the screen.

Install the MPEG Card in the processor direct slot.

Basics TV Tuner Module - 15

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/FM Radio Tuner Card - 16

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/FM Radio Tuner Card - 17

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/FM Radio Tuner Card - 18

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/FM Radio Tuner Card - 19

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 External Video Connector - 20

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
3/4-inch, 22-pin slot on the logic board.

Basics Apple Presentation System - 21

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 CRT and Degauss Frame - 22
