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
