Basics TV/FM Radio Tuner Card - 20

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 - 21

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 - 22

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

• 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 - 24

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 Sound - 26

Sound

The sound system supports 8-bit and 16-bit stereo sound
output and input. It can create sounds digitally and play the
sounds through the internal speakers or send the sound
signals through the sound output jacks.

Digitizing Sound

The 6400 and 6500 computers digitize and records sound as
16-bit samples. It can use two of these sampling rates—
11k, 22k, or 44k samples per second. It can record sound
from the following sources:

• Built-in microphone

• Microphone connected to the sound input jack

• Video input module

• Compact disc in the CD-ROM player

Basics Sound - 27

Sound Output

The 6400 and 6500 computers have one built-in
speaker/subwoofer and two sound output jacks, one on the
front and one on the back. Both output jacks are connected to
the sound amplifier. Inserting a plug into either jack
disconnects the internal speakers. The jack on the front is
intended for headphones, and the jack on the back is intended
for external speakers. The rear jack is muted when
headphones are plugged in the front jack.

Basics Sound - 28

Sound Input

One sound input port for stereo sound input supports the
Apple PlainTalk Microphone, and it supports non-Apple
microphones. It also supports a standard stereo (miniplug­to-RCA) cable adapter for connecting stereo equipment to
the computer.

Basics Expansion Bay - 29

Expansion Bay

The expansion bay includes audio, data, and power
connectors for adding a SCSI CD-ROM or other SCSI device.
The bay is configured for 5.25-inch devices, but with
modification to the carrier, a 3.5-inch SCSI device could be
installed. In some computers, the bay may already be
occupied by a Zip drive.

Basics Expansion Bay - 30

Chassis Revision Identification

There are two versions of the Metal Chassis Assembly for
the Power Macintosh/Performa 6400 and 6500 series
machines. Part number 922-2272 Chassis, Metal, Rev. A
should be used for all Power Macintosh/Performa 6400
series machines with the exception of the PM/Perf 6400/
200 with Zip Drive. Part number 922-2707 Chassis,
Metal, Rev. B should be used for all Power Macintosh 6500
series machine as well as the PM/Perf 6400/200 with Zip
Drive.

Basics Intelligent Device Electronics (IDE) Hard Drive - 31

Intelligent Device Electronics (IDE) Hard Drive

The internal hard drive uses IDE technology, commonly used
in DOS-compatible systems, and the standard ATA-2 or IDE
interface. The hard drive has a standard 40-pin ATA
connector, and a separate 4-pin power connector.

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. Six external SCSI devices may be daisy-chained
through the external SCSI port.

Basics Peripheral Component Interconnect (PCI) Technology - 32

Peripheral Component Interconnect
(PCI) Technology

The 6400 and 6500 computers offer a peripheral
component interconnect (PCI) expansion bus. Because the
PCI bus is an industry standard, most existing PCI 2.0­compliant cards (with the addition of a Macintosh OS­specific 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 Peripheral Component Interconnect (PCI) Technology - 33

Note:

PCI expansion slots are compatible with all PCI 2.0
specification-compliant cards with the addition of
Macintosh-OS-specific software driver. Nubus cards
be used in this expansion slot. PDS cards for the Macintosh
LC family, the Macintosh Quadra 630 computer, or cards
that operate in the I/O expansion slot in Power Macintosh
5200 and 6200 computers are
expansion slots.

Basics Communications - 34

Communications

The logic board has a communications slot for adding a
communications module without occupying the PCI
expansion slots. The slot uses a PCI bus, and supports the
following cards:

• 10Base-T (twisted pair) Ethernet card

• 10Base-2 (thin coax) Ethernet card

• AAUI (Apple standard) Ethernet card

• 28.8 bps fax/data modem card

Note:

This PCI bus-compatible slot is
communications cards for the Macintosh LC family and
Macintosh Quadra 630 or with cards that operate in the
Power Macintosh 5200 and 6200 communication slots. The
exception is that cards that do not use the bus, such as serial
modem cards, have been designed to work in either type of
communications slot.

GeoPort Technology

Geoport is a hardware and software communications
architecture that has been optimized for computer­telephony integration. It has three main attributes:

• It lets any GeoPort-compatible 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 Dual In-Line Memory Modules (DIMMs) - 37

Dual In-Line Memory Modules (DIMMs)

The 6400 and 6500 come with 16 MB of DRAM. Two 168­pin sockets allow for memory expansion.

The 6400 and 6500 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.

1K or 2K refresh count. For the Power Macintosh 6500, use
168-pin, 5-volt buffered extended data out (EDO) mode, 60
ns or faster, 2K refresh rate DIMMs. Do
a 4K refresh count.

Also, the JEDEC MO-161 specification shows three possible
heights for the 8-byte DIMM. For these computers, use only
the shortest of the three (1.100 inches). Taller DIMMs put
excessive pressure on the DIMM sockets due to mechanical
pressure inside the case.

Performa/Power Macintosh 6400

DRAM DIMMs can be installed individually. However, if you
wish 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, thus providing for 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) - 40

Power Macintosh 6500

The 8-byte DIMMs can be installed one or more at a time.
The 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 installed DIMMs is configured as a contiguous array of
memory.

The DIMM slots accommodate 168-pin, 5-volt, fast-paged
and EDO DRAM DIMMs. The largest DIMM supported is a
two-bank DIMM holding 64 MB.

6500 Supported Monitor Resolutions

The system software on Power Macintosh 6500 computers
allows selecting monitor resolutions above 1152 x 870. But
these higher resolutions cause poor video output, such as
misaligned or skewed video, low brightness, and so on.

Monitors connected to Power Macintosh 6500 computers
should not be set to resolutions above 1152 x 870. Check the
Monitors and Sound Control Panel to make sure the

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 or not 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.)
