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 - 20 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.
Basics TV Tuner Module - 21 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.
Basics TV Tuner Module - 22 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.
Basics TV Tuner Module - 23 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.
Basics TV Tuner Module - 24 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.
Basics Digital Audio Video (DAV) Technology - 26 Video Input Card DAV Connector DAV Connector PCI Card with DAV Note: The DAV connector on the video input card provides some of the functionality of the DAV connectors found on the Power Macintosh 7100 and 8100 models, and the Macintosh Quadra AV models, but it is not compatible with any of those connectors.
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) - 29 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.
Basics GeoPort Technology - 30 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 - 31 • 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.
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.
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.
Basics CRT and Degauss Frame - 36 CRT and Degauss Frame The CRT and degauss frames are precisely matched at the factory and must be removed and replaced as a unit.
Basics Front View - 37 Front View Color Display Built-In Microphone CD-ROM Drive (optional) Floppy Disk Drive CD-ROM Drive Sound Control Buttons Screen Control Buttons Power Key Stereo Speakers Tilt-and-Swivel Base Remote Control Sensor Power-On Light Keyboard Headphone Jack Mouse
