Summary of Features 1
Here is a summary of the hardware features of the Macintosh Performa 6400 computer.
■ Microprocessor: PowerPC 603e microprocessor running at 160, 180, and 200 MHz.
■ RAM: 8 MB soldered to the main logic board; expandable to 136 MB using 168-pin
JEDEC-standard DIMM devices. Two DIMM slots are provided for DRAM expansion.
■ ROM: 4 MB soldered on main logic board; 64-bit ROM data bus width.
■ Cache: 256 KB second-level (L2) cache on a 160-pin DIMM card (optional).
■ Video display modes supported on built-in monitor port: 640 by 480 and 800 by 600 @
16 bits per pixel, 832 by 624 and 1024 by 768 @ 8 bits per pixel; 1 MB DRAM frame
buffer on the main logic board.
■ Video input: optional video-in card allows video input through RCA and S-Video
connectors; a 60-pin DAV (digital audio video) connector on the video-in card
supports an optional video card for real-time video display, capture, and overlay. An
adapter cable provides backward compatibility with DVA (digital video application)
cards designed for the Power Macintosh 5200 computer.
■ Video output: optional DAV PCI cards provide video output.
■ Sound: 16 bits/channel stereo sound input and 16 bits/channel stereo sound ouput
using SRS® (surround retrieval system), an external jack for sound in, a front jack for
headphones, a rear jack for stereophonic speakers, and one built-in speaker/
subwoofer. SRS stereo surround sound can be turned on or off through the Sound
panel of the Monitors and Sound control panel. SRS is incorporated in the design
under license from SRS Labs, Inc.
■ TV/FM receiver: optional internal TV/FM tuner with F-type antenna connector.
■ Remote control: infrared for TV/FM tuner.
■ Hard disks: one internal 3.5-inch ATA (IDE) hard disk with 2.4 GB or larger capacity
and an external SCSI port for additional SCSI devices. PIO, singleword DMA, and
multiword DMA data transfers are supported.
■ Expansion bay: allows addition of an internal 5.25-inch SCSI device.
■ Floppy disk: one internal 1.4 MB Apple SuperDrive.
■ CD-ROM drive: internal 8X-speed CD-ROM drive; the expansion bay supports the
addition of another CD-ROM drive.
