The Power Macintosh 7200 is a desktop Macintosh with a PowerPC 601 processor soldered to the logic board and three PCI expansion slots. Apple introduced the 7200/75 and 7200/90 on 8 August 1995, together with the 7500 and 8500, and added the 7200/120 on 22 April 1996.[1][2][3] It replaced the Power Macintosh 6100 as Apple's lowest-priced multi-slot model and shares its desktop case with the 7500.[4] Its code name, Catalyst, appears on Apple's logic board schematic.[5] Wikipedia records that it was sold until February 1997, when the Power Macintosh 4400 replaced it as the entry-level model.[6]
The 90 MHz model was sold in Japan as the Power Macintosh 7215/90,[7] and the server version was the Apple Workgroup Server 7250, which Apple services from the same manual.[8]
Models
[edit | edit source]| Model | Introduced | Processor / bus | Standard RAM | Hard drive | CD-ROM |
|---|---|---|---|---|---|
| 7200/75 | 8 August 1995 | 75 / 37.5 MHz | 8 MB | 500 MB | AppleCD 600i |
| 7200/90 | 8 August 1995 | 90 / 45 MHz | 8 or 16 MB | 500 MB or 1 GB | AppleCD 600i, or none |
| 7200/120 | 22 April 1996 | 120 / 40 MHz | 8 or 16 MB | 1.2 GB | AppleCD 600i or 1200i |
| 7200/120 PC Compatible | 22 April 1996 | 120 / 40 MHz | 8 or 16 MB | 1.2 GB | AppleCD 600i |
Dates and bus speeds from Apple's specification pages;[1][2][3] configurations from the developer notes and the Service Source (pp. 7, 36).[4][9][8] The PC Compatible model shipped with a PC Compatibility Card in one PCI slot.[10] Apple offered a 7-inch card with a 100 MHz 5x86 and a 12-inch card with a 100 MHz Pentium (SS pp. 37–38).[8]
Apple's April 1996 developer note also lists a 7200/100 (100 MHz, 50 MHz bus, 800 MB disk). The Service Source and Apple's specification pages do not include it.[9][8] The same note gives a 256 KB L2 cache on one 7200/120 configuration; the other models had the cache slot empty.[9]
Hardware
[edit | edit source]Processor and logic board
[edit | edit source]The 601 is soldered to the logic board, so the 7200 has no processor card slot. Its processor bus runs at half the processor clock (37.5 or 45 MHz) on the 75 and 90 MHz models, and the PCI bus at 33 MHz (dev note pp. 12, 15).[4] The custom chips are Platinum (memory and video controller), Iridium (data buffer and QuickDraw acceleration), Bandit (PCI bridge), Grand Central (I/O, DMA and the SWIM III floppy controller), Curio (Ethernet, SCSI and serial), Cuda (soft power, resets, ADB, PRAM and clock) and AWACS (sound) (pp. 14–16); the Service Source adds that Cuda maintains the PRAM (SS p. 17).[4][8]
Apple made five versions of the 7200 logic board: one 75 MHz, two 90 MHz and two 120 MHz. One of each pair carries an auxiliary processor fan that plugs into the board at J70. Apple warns not to unplug the Peltier device (one red and one black wire) that runs from the processor to the logic board, or the board will be damaged (SS p. 22).[8]
Memory and video
[edit | edit source]There is no RAM on the logic board. The four DIMM slots take 5 V, 168-pin, fast-page-mode DIMMs of 70 ns or faster, installed singly in any order; at least one must be fitted. The Platinum controller supports linear memory only, so matched pairs give no interleaving gain (SS pp. 9–11; dev note p. 14).[8][4] Low End Mac advises against EDO DIMMs in the 7200.[11]
The board has 1 MB of VRAM soldered on. One 1 MB VRAM DIMM in slot 1 gives 2 MB; three DIMMs in slots 1, 2 and 3 give 4 MB, and slots 2 and 3 must be filled together. VRAM DIMMs are 112-pin, 70 ns or faster; the VRAM SIMMs of earlier Power Macintosh models do not fit (SS pp. 4, 35, 125).[8] With 1 MB the DB-15 port gives 16-bit colour up to 832 × 624; with 4 MB it reaches 24-bit at 1024 × 768 and 16-bit at 1280 × 1024 (SS p. 35).[8]
Storage and expansion
[edit | edit source]The three PCI slots accept PCI 2.0 cards with a Mac OS driver; NuBus cards do not fit (SS p. 33).[8] Apple advises using the middle slot for third-party cards, for clearance under the expansion card cover (SS p. 118).[8] The internal and external SCSI ports both run at up to 5 MB/s (dev note p. 5).[4] If cables are plugged into both Ethernet ports, the computer uses the 10BASE-T port (SS p. 14).[8]
Power supply
[edit | edit source]The supply is not self-configuring. A switch on the back must be set to 115 for 100–130 V or 230 for 220–270 V (dev note p. 9); the Service Source says it must be set to 115 V in the US (SS p. 39), and the User's Guide repeats the warning in its setup steps.[4][8][12] Apple rates the computer at 150 W maximum, excluding the monitor (SS p. 39).[8] Two cables run to the logic board: a 22-pin cable carrying +5 V and ±12 V and a 10-pin cable carrying 3.3 V (SS pp. 23, 100, 130).[8] The service part is 661-0920 (SS p. 157). The label carries Apple's assembly number 614-0039, which does not identify the maker: the supply in one 7200 was a Delta DPS-150GB, and ASTEC-made 614-0039 supplies have been found in the 7500.[8][13][14]
Known faults
[edit | edit source]Apple's symptom charts record these model-specific problems:[8]
- On machines with serial numbers CK634 to CK637, XB634 to XB637, SG634 to SG637 and FC634 to FC637, a 1.2 GB hard drive labelled "1280S p/n TM12S012" and "REV 02-B" can stop the computer powering off, or leave the LED lit after shutdown. Only revision 02 drives cause it; Apple's cure is to replace the drive (pp. 51–52).
- A 7200/90 that hangs or times out when moving large files over certain Ethernet repeaters may have Ethernet clock jitter. Revised boards carry a 20 MHz oscillator at G1, next to the internal SCSI connector and the Curio chip; four blank pads there mark an unrevised board. Machines with serial numbers xx545 and later should already have the revised board (pp. 66–67).
- AppleCD 600i drives can stutter on CD+ or CD-R discs or fail to mount a disc; Apple replaced the drive (p. 64).
- Intermittent shutdowns can be thermal protection. Clear the vents and allow 30 to 40 minutes; on boards with the J70 fan, check that it is plugged in and running (p. 49).
Owners of this case family report power supplies that click without starting, and one 7200 supply had a cracked circuit board.[14][13] The clock battery is a 3.6 V lithium half-AA cell (Apple part 742-0029 on the bill of materials bound with the schematic); a leaking cell corrodes the board, so remove an old one.[1][5] See Battery Explosion, Capacitor or Corrosion Damage.

| Speaker | 922-1639 |
| EMI clip | 922-1721 |
| Top housing | 922-1642 |
Apple's 7600 upgrade kit replaces the 7200 logic board with a 7600 board, which needs a separate processor card; the J70 fan must not be refitted (SS pp. 144–155).[8]
