The Power Macintosh 7600 is the Power Macintosh 7500 with a PowerPC 604 processor card in place of the 7500's 601. Apple gave it a new model number because the processor type changed.[1] Apple introduced the 7600/120 on 22 April 1996, the 7600/132 on 3 August 1996 and the 7600/200, sold only in Japan, on 17 February 1997.[2][3][4] Wikipedia gives 1 April 1996 for the first model.[5] The 7600 shares its case, logic board design and Service Source with the 7500 and the 7300, and those machines share their maintenance guides.[6]
Models
[edit | edit source]| Model | Introduced | Processor / bus | RAM | Hard drive | CD-ROM |
|---|---|---|---|---|---|
| 7600/120 | 22 April 1996 | 604, 120 / 40 MHz | 16 MB | 1.2 GB | AppleCD 600i (4×) |
| 7600/132 | 3 August 1996 | 604, 132 / 44 MHz | 16 MB | 1.2 GB | AppleCD 1200i (8×) |
| 7600/200 (Japan) | 17 February 1997 | 604e, 200 / 50 MHz | 32 MB | 2 GB | AppleCD 1800i (12×) |
Dates and bus speeds from Apple's specification pages and developer notes;[2][3][4][1][7] standard configurations from the Service Source (pp. 13–14, 50–51).[6] The developer note gives the 7600/200's drive as an AppleCD 1600i; the Service Source says 1800i.[7][6]
Differences from the 7500
[edit | edit source]- The processor card carries a PowerPC 604 (120 or 132 MHz) or 604e (200 MHz) instead of the 7500's 601, and a 256 KB level-2 cache is standard (SS p. 6; Apple's specification pages).[6][2]
- The 7600/200 uses 60 ns EDO DIMMs; the 120 and 132 MHz models use 70 ns DIMMs (SS p. 43).[6]
- The 7600/200 has a security bar that covers the latches of the top housing (SS p. 164).[6]
- Fitting a 132 MHz card requires an EMI grounding clip over the top chassis wall, touching the card's heat sink (SS pp. 136–137).[6]
The video input, AV panel and DAV slot are the same as the 7500's; like the 7500, the 7600 has no video output.[7] Apple sold a 7600 logic board upgrade kit for the Power Macintosh 7200; it needs a separate processor card (SS p. 168).[6]
Known faults
[edit | edit source]- On machines with serial numbers XB633XXX8L or lower, Apple's cure for intermittent crashes with a 132 MHz card is to replace the card (SS p. 66).[6]
- Processor cards of 180 MHz and faster cause errors when floppy disks are initialised, or leave a 1.4 MB disk showing only 1 MB; system software 7.5.4 or the Power Mac Format Patch cures it (SS p. 83).[6]
- The 2/3/4/6 GB Firmware Utility fixes drives that fail to wake from sleep (SS pp. 58–59).[6]
- Owners report 614-0039 power supplies that click without starting.[8]
The faults Apple lists for the 7500, the 7300 and the shared case are on Power Macintosh 7500 Troubleshooting. The clock battery is a 3.6 V lithium cell.[2] See Battery Explosion, Capacitor or Corrosion Damage.
