TOPIC


    This article contains a list of technical specifications for the Power Macintosh 7200/75 and 7200/90.

DISCUSSION


    Microprocessor
    --------------
    * PowerPC 601 microprocessor running at 75 MHz (7200/75 model)
    * PowerPC 601 microprocessor running at 90 MHz (7200/90 model)
    * Integrated floating-point unit and 32K cache

    Memory
    ------
    * 8 MB of RAM, expandable to 256 MB via 4 DIMM sockets
    (Note: There is no RAM soldered to the logic board. The DIMM sizes installed
    at the factory will vary according to availability; there will be either two
    4 MB DIMMs or one 8 MB DIMM.)
    * Level 2 (L2) Cache: L2 Cache Slot for Optional 256KL2 cache on a
    160-pin DIMM. (These computers theoretically support 512K and 1 MB of L2
    cache, but these configurations have not been tested and are not supported by
    Apple.)
    * 4 MB of ROM
    * 1 MB of Video RAM (VRAM) in both the Power Macintosh 7200/75 & 7200/90 models

    Disk Drives
    -----------
    * Internal 500 MB SCSI hard disk
    * Internal Apple SuperDrive floppy disk drive
    * Accepts high-density 1.4 MB disks and 800K disks
    * Reads, writes, and formats Macintosh, Windows, MS-DOS, OS/2,
    and ProDOS disks
    * Internal AppleCD 600i quadruple-speed CD-ROM drive
    * Expansion bay for additional 3.5-inch hard disk

    Interfaces
    ----------
    * Three PCI expansion slots compatible with PCI 2.0-compliant cards
    (Note: These slots are not NuBus-compatible)
    * Two high-speed DMA serial (RS-232/RS-422) ports compatible with
    LocalTalk and GeoPort cables
    * 10Base-T and AAUI-15 Ethernet connectors
    * Internal and external SCSI bus (up to 5 MB/s)
    * Apple Desktop Bus (ADB) expansion port
    * Mini jacks for stereo audio input and output
    * 16-bit audio
    * Up to 44.1-kHz sampling rate
    * DB-15 connector for monitor

    Audio System
    ------------
    * Custom sound circuitry, including stereo generator (digital-to-analog
    converter, or DAC)*capable of driving stereo miniplug headphones or audio
    equipment*and stereo sampling hardware (analog-to-digital converter, or
    ADC) for recording stereo sound
    * 16-bit stereo input and output
    * Sample rates of 44.1 and 22.05 kilohertz (kHz)
    * Input line level: 2 volts peak-to-peak nominal, into 6.5-Kilohm (k*)
    impedance
    * Output line level: 2.2 volts peak-to-peak nominal, into 1 k* impedance
    * Input through output SNR*: >74 decibels (dB) typical
    * Bandwidth: 10 Hz*19 kHz (+/* 2 dB) at 44.100 kHz sample rate
    * THD+N*: Less than 0.06%; measured 30 Hz*16 kHz with a 2-Vpp sine wave
    input
    *SNR is signal-to-noise ratio; THD+N is total harmonic distortion plus noise.

    Graphics Support
    ----------------
    * VRAM-based accelerated graphics
    * 1 MB of VRAM, expandable to 4 MB
    * 64-bit data path to VRAM (with 2 MB of VRAM)
    * Support for display resolutions of up to 1,280 by 1,024 pixels
    * 24-bit color of up to 1,024- by 768-pixel resolution
    * Refresh rate of up to 75 Hz

    GeoPort Telephony*
    ------------------
    * 14.4-Kbit/s modem support
    * V.17 fax support
    * GeoPort Fax and GeoPort Telephony software included
    * Speakerphone and answering-machine capability
    * Requires GeoPort Telecom Adapter

    Clock/Calendar
    --------------
    * Custom integrated circuit with long-life battery

    Keyboard And Mouse
    ------------------
    * Supports ADB keyboards with numeric keypads
    * Comes with an ADB Mouse II

    Electrical Requirements And Compliance
    --------------------------------------

    ----------------------
    * Maximum current draw for all devices: 500 mA
    . (a maximum of three ADB devices is recommended)
    * Mouse draws 10 mA
    * Keyboard draws 25 to 80 mA (varies with keyboard used)
