Features

Here is a list of the features of the PowerBook computer. Each feature is described in a later chapter, as indicated in the list.

• Processor: The computer has a PowerPC G3 microprocessor running at a clock speed of 400 or 500 MHz. For more information, see G3 Microprocessor.
• Cache: The computer has a backside L2 cache consisting of 1 MB of fast static RAM. The ratio of the microprocessor and backside cache clock speeds is 5:2. See Backside Cache.
• RAM: The computer has two standard SO-DIMM expansion slots for SDRAM modules. The computer comes with 64 or 128 MB of SDRAM installed. RAM is expandable up to 512 MB total, using currently available memory devices. See RAM Expansion Slots.
• ROM: NewWorld ROM-in-RAM implementation with 1 MB of boot ROM. For information about the ROM, see Boot ROM. For information about the ROM-in-RAM implementation, see ROM in RAM.
• Hard disk storage: The computer has a built-in hard disk drive with a capacity of 6, 12, or 18 GB. For more information and developer guidelines for alternative hard drives, see Hard Disk Drive.
• Display: The computer has a 14.1-inch TFT display with XGA resolution (1024 x 768 pixels). See Flat Panel Display.
• External monitor: All configurations support dual displays, with a standard VGA video connector for an external video monitor with resolution up to 1280 by 1024 pixels and an S-video connector for PAL and NTSC video monitors. See External Monitors.
• Video RAM: The ATI RAGE Mobility 128 graphics controller contains 8 MB of video SDRAM, which supports millions of colors on the internal display or an external monitor. See Video Display Subsystem.
• Graphics acceleration: The ATI RAGE Mobility 128 graphics controller provides 2D and 3D acceleration. For more information, see Video Display Subsystem.
• Battery bays: The computer has two battery bays, one on either side. The computer can operate with the AC power adapter or with one or two batteries installed. Each battery uses lithium ion cells and provides 50 Watt-hours at a nominal 10.8 V.
• Expansion bay: The battery bay on the right side of the computer is also an expansion bay for a DVD drive or other IDE devices. Storage devices in the expansion bay can be removed and replaced while the computer is operating. For more information, see Expansion Bay.
• DVD-ROM drive: The computer is shipped with a DVD-ROM drive installed in the expansion bay. The drive can also read DVD-RAM disks. For more information, see DVD-ROM Drive.
• CardBus slot: The computer has a CardBus slot that accepts one Type I or Type II PC card or CardBus Card. For more information, see CardBus Slot.
• USB ports: The computer has two USB ports for an external keyboard, a mouse, and other USB devices, described in USB Ports.
• FireWire ports: The computer has two IEEE-1394a high-speed serial FireWire ports, which support transfer rates of 100, 200, and 400 Mbps. For more information, see FireWire Ports.
• Modem: The computer has a built-in modem with 56 Kbps data rate and V.90 support. For more information, see Internal Modem.
• Ethernet: The computer has a built in Ethernet port with an RJ-45 connector for 10Base-T and 100Base-TX operation. For more information, see Ethernet Port.
• Infrared link: The computer has an IrDA infrared link capable of transferring data at up to 4 Mbits per second. For more information, see Infrared Communication Link.
• Wireless LAN: An AirPort Card wireless LAN module is available as a configure-to-order option or as a user-installable upgrade. For more information, see AirPort Card Wireless LAN Module.
• Sound: The computer has a built-in microphone and stereo speakers as well as a line-level stereo input jack and a stereo headphone jack. See Sound System
• Keyboard: The keyboard has an embedded numeric keypad and inverted-T arrow keys. Some of the function keys are used to control the display brightness and speaker volume; the other function keys are programmable by the user. See Keyboard.
• Trackpad: The integrated flat pad includes tap/double tap and drag features. For more information, see Trackpad.
• Weight: The computer weighs 2.8 kg (6.1pounds).
• Size: The computer is 322.6 mm (12.7 inches) wide, 264.2 mm (10.4 inches) deep, and 43.2 mm (1.7 inches) thick.
