ThePower Macintosh 6400 (also sold under variations of the namePerforma 6400) is apersonal computer designed, manufactured and sold byApple Computer from August 1996 to August 1997. It is the onlyMacintoshmini-tower system to be branded as aPerforma, and alongside thePerforma 6360 was the last new Performa-branded model introduced by Apple.
The 6400 and its Performa variants were discontinued in favor of the uniformly-namedPower Macintosh 6500 in August 1997.
Logic board: The logic board, code-named "Alchemy", is shared with thePower Macintosh 5400 all-in-one andPerforma 6360 desktop models. Alchemy is generally believed to be superior to its 5200/6200 predecessors since it had a 64-bit data path to main memory.[2]
CPU: All 6400 models use aPowerPC 603ev processor that is soldered to the computer's logic board and cooled by a fanless heat-sink. Though initially considered non-upgradable, CPU upgrades did come to market that overrode the fixed CPU by use of theLevel 2 cache slot.[3]
Sound: The new "InstaTower" case features an integratedsubwoofer speaker and supports SRS surround-sound. A knob on the back of the case controls the bass level of the subwoofer; this knob only works if external speakers are connected, otherwise the internal speaker provides full sound range. There are two audio output jacks, one on the front and one on the back. Headphones plugged into the front jack will disable the internal speaker and rear jack.[4]
Expansion: There are two PCI expansion slots as well as a dedicated communications slot that supports AAUI, Ethernet and fast modem cards. The communication slot is not compatible with similar slots on other Macintosh computers.Processor Direct Slot (and thereforeNuBus) cards are not supported.
Operating system: The Performa 6400/180 and 6400/200 were shipped with System 7.5.3 Revision 2.1; this particular release was specific to these machines as there were stability problems with System 7.5.3 Release 2 on the new hardware, especially with the video card and transferring files over LocalTalk.[5]
All Performa models shipped withSurfWatch, a product fromSpyglass, Inc. that provides adult content filtering capability;[6]content-control software was a significant issue at the time due to the recent passage of theCommunications Decency Act in the United States.
