Macintosh Performa 6400
The Macintosh Performa 6400 is a mini-tower Macintosh with a PowerPC 603ev at 180 or 200 MHz, sold as the Performa 6400/180 and 6400/200 from August 1996. Apple's specification sheets date both 5 August 1996; EveryMac gives 7 August 1996 and a discontinuation date of 1 August 1997.[1][2][3] Apple services the Performa 6400, the Power Macintosh 6400, the international Performa 6410 and 6420, and the Power Macintosh 6500 with one manual, the Performa/Power Macintosh 6400 and 6500 Series Service Source.[4]
Wikipedia describes the logic board as the design shared with the Power Macintosh 5400 and Performa 6360, which it calls "Alchemy".[5]

Hardware
[edit | edit source]The logic board is on the left as seen from the back. It needs no other parts removed first: take out the two screws holding it to the rear panel and pull it out by its two plastic tabs.[4] Replacement boards are 661-1452 (180 MHz) and 661-1453 (200 MHz); the power supply is 661-1169.[4] Two metal chassis were made: 922-2272 (Rev. A) for the 6400 series except the 6400/200 with Zip drive, and 922-2707 (Rev. B) for that model and the 6500. The internal cable harness is part of the chassis and is not sold separately.[4]
Voltage switch
[edit | edit source]The power supply is not auto-ranging. Its voltage switch must be set correctly to avoid damaging the computer. Set it with a screwdriver to "115" for 100-130 V or "230" for 200-270 V.[4] Apple's symptom chart for a CD-ROM drive with no power, or not recognised, includes checking that the supply is set to the right voltage and replacing the supply if the switch was in the wrong position.[4]
Memory
[edit | edit source]The Performa 6400, 6410 and 6420 take 168-pin fast-page-mode DIMMs, 70 ns or faster, with a 2K refresh rate. The Power Macintosh 6400 and the Performa 6400/200 with Zip drive take EDO DIMMs, 60 ns or faster, 1K or 2K refresh. Apple says not to use 4K-refresh DIMMs, and to use only the shortest of the three JEDEC DIMM heights (1.100 in), because taller modules put too much pressure on the sockets inside the case.[4] DIMMs can be fitted singly; matched pairs allow memory interleaving.[4]
Cache, communications and modem
[edit | edit source]The optional 256K level 2 cache is a 160-pin card with its own controller. Apple did not support third-party cache cards, and the slot does not take cache cards from earlier Power Macintosh models.[4] Wikipedia notes that third-party processor upgrades were later made for this slot.[5]
The communications slot uses the PCI bus. It does not take the communications cards of the LC family, Quadra 630 or Power Macintosh 5200 and 6200, except cards that do not use the bus, such as serial modem cards.[4] Some Performa 6400s shipped with an internal GeoPort modem and some with a Global Village modem, and the communications software only works with the original type. The last three characters of the serial number identify it:[4]
| Modem | 6400/180 | 6400/200 |
|---|---|---|
| Global Village Platinum | 7U7 | 836 |
| GeoPort | 95R | 95S |
Things that are not faults
[edit | edit source]- With external speakers attached, the subwoofer works as a bass speaker; without them it plays full-range sound. The subwoofer balance control only works when external speakers are connected.[4]
- A plug in either output jack disconnects the internal speaker, and the rear jack is muted while headphones are in the front jack.[4]
Battery
[edit | edit source]Apple's specification sheets give the battery as 4.5 V alkaline. The Service Source's battery replacement procedure carries Apple's warning that the "lithium battery in the computer could explode" if mishandled, so the two Apple documents disagree on the chemistry.[1][4] Apple's test is to take out the logic board, measure the battery on the 10 V DC range and replace it below 3.0 V. It sits on a hook-and-loop base with a plug-in connector.[4] Check the markings on the pack before cleaning up a leak: alkaline leakage is neutralised with a weak acid such as vinegar, lithium cells with bicarbonate. See Battery Explosion, Capacitor or Corrosion Damage.
To reset the logic board, take it out, unplug the battery, wait five to ten minutes and plug it back in.[4]
From Apple's symptom charts
[edit | edit source]| Symptom | Apple's cures, in order |
|---|---|
| Machine does not start | Reset the logic board; replace the power supply; replace the logic board[4] |
| Starts from the power switch but not from the keyboard | Check the keyboard connection; try a known-good keyboard[4] |
| No video, fan running | Check the monitor connection; try a known-good monitor; replace the monitor-out card; remove the DIMMs and refit them one at a time to find a bad one; replace the logic board; replace the power supply[4] |
| Sad Mac icon with black vertical lines and a screeching sound | Replace the DIMMs; replace the logic board[4] |
| Flashing "?" with the 1.6 GB (661-1107) or 2.4 GB (661-1202) ATA hard drive, sometimes cured by a restart | Check the system software; replace the drive if its serial number falls between XXX6099XXXXX and XXX6131XXXXX[4] |
| SCSI device not recognised | Check termination and cable; check the device's software; use the 6360/64xx/54xx Update disk to correct a possible SCSI timing problem[4] |
| No sound from the speaker | Check the speaker connection to the logic board; replace the speaker assembly (if headphones work, the speaker assembly is at fault)[4] |
The start-up chords and Sad Mac codes are on Sad Mac Error Codes.
