The Power Macintosh 5500 is an all-in-one Macintosh with a built-in 15-inch display and a PowerPC 603e processor at 225, 250 or 275 MHz. Apple dates the 5500/225 to 17 February 1997 and the 5500/250 to 1 September 1997.[1][2] It replaced the Power Macintosh 5400 in the same enclosure, and Apple services both with one manual, the Power Macintosh/Performa 5000 Series Service Source, which says that "models in the 5500 series are made entirely with Rev. B parts".[3] Apple's developer note pairs it with the Power Macintosh 6500, and the two use the same logic board part numbers.[4]
Models
[edit | edit source]| Model | Markets | Standard features and Apple's listed configurations |
|---|---|---|
| 5500/225 | Worldwide | 225 MHz, 16 MB, 2 GB or larger drive, 12× CD-ROM. US education: 32 MB, 24× CD-ROM, Ethernet, Mac OS 8.0. Japan: 32 MB, 4 GB, 24×, 33.6 modem. Europe: 32 MB, 2 GB, 24×, 33.6 modem |
| 5500/250 | Japan and Australia; US education | As the 5500/225 at 250 MHz. A graphite configuration adds 32 MB, 4 GB, 24× CD-ROM, video in, 33.6 modem and Mac OS 8.0. The US education version adds video in, NTSC out and Ethernet |
| 5500/275 | Europe | As the 5500/225 at 275 MHz. A graphite configuration adds 32 MB, 4 GB, 24× CD-ROM, 512K L2 cache, TV/FM tuner, video in, 33.6 modem and Mac OS 8.0 |
Source: pp. 9–14.[3] Low End Mac adds that Xemplar sold a 225 MHz education version in the UK as the "Power Macintosh One", that a black 275 MHz "Director's Edition" was sold in Australia, and that a reader reported many Australian 5500s shipped in 1998 without an L2 cache.[5]
Hardware
[edit | edit source]| Item | Figure |
|---|---|
| Processor | PowerPC 603e at 225, 250 or 275 MHz; 64-bit bus (pp. 45–46). Apple's specification pages give a 50 MHz bus |
| RAM | 16 or 32 MB, none soldered; two JEDEC 168-pin DIMM slots for 5 V buffered EDO DIMMs, 60 ns or faster, 2K refresh; 128 MB maximum. The slots also take 5 V fast-page-mode DIMMs, but mixing the two types may stop the board running at fast-page timings (pp. 10, 47–49) |
| Video | 2 MB SGRAM frame buffer with 2D and 3D acceleration; 640 × 480 to 832 × 624 at 32 bits, 1024 × 768 and 1152 × 870 at 16 bits, 1280 × 1024 at 8 bits (pp. 9–10, 58) |
| Level-2 cache | Optional 256K card in a 160-pin slot; 512K on the 5500/275 (p. 48) |
| Storage | 1.4 MB SuperDrive; 2 GB or larger IDE drive; 12× or 24× CD-ROM (pp. 50–51) |
| Expansion | One 32-bit PCI slot for 7-inch cards; video-in (DAV) slot; communications slot; optional TV/FM tuner (pp. 52–55) |
| Sound | 16-bit recording at 11, 22 or 44 kHz; stereo speakers with SRS surround-sound mode (pp. 57–58) |
| Display | 15-inch shadow-mask CRT, 12.8 inches viewable, 0.28 mm dot pitch (p. 59) |
| Electrical | 100–240 V AC, 47–63 Hz; 125 W; 2.5 A and 220 W maximum under all line and load conditions (p. 66) |
| Cooling | The fan speed follows the temperature inside the enclosure; the processor has its own small fan (p. 9) |
Source: service manual at the pages given.[3] Apple's specification pages give 220 W, 4 A and a 32 MB minimum, and a weight of 47 lb; the manual's weight line ("17 lb ... 19 lb (21.15 kg)") does not agree with itself.[1]
Clock battery
[edit | edit source]Apple's specification pages give the battery as 4.5 V alkaline.[1] Apple's test is to replace it below 3.0 V (pp. 245–246).[3] Alkaline leakage is caustic; see Battery Explosion, Capacitor or Corrosion Damage.
High voltage
[edit | edit source]The analogue board and CRT carry lethal voltages. Follow the CRT Discharge Procedure before working near them. The 5500 uses the Rev. B analogue board, on which Apple's high-voltage adjustment sets 29.5 V DC ± 0.1 V at the cathode of D703 with VR702, after the set has warmed up for ten minutes (pp. 301–305).[3] The full adjustment procedure is on Macintosh Performa 5400 General Maintenance.
Known faults
[edit | edit source]Apple documents three 5500 faults in the service manual, and a replaceable processor fan.[3]
Video jitter
[edit | edit source]Pixels shimmer at the edge of the screen, dialog boxes or windows on 5500/225s with serial numbers TY705xxxxx to TY715xxxxx. Replace the logic board with a reworked 661-1322 board. On the underside of the board, resistor R363 reads "100" on a board that has not been reworked and "101" on one that has (pp. 83, 253–254).
Software installation errors
[edit | edit source]"Unable to decompress file ... because of a data mismatch error", hangs, freezes or Type 10 errors during installation, on 5500s from TY705xxxxx to TY716xxxxx. The cause is an OPC-made logic board (marked "OPC" along the edge) with an incompatible L2 cache DIMM. Read the smaller chips on the back of the cache DIMM: a five-digit number such as 32384 is compatible, a four-digit number such as 3384 is not, and Apple's replacement cache is 661-1477 (pp. 97, 255–259).
Freezes during video capture
[edit | edit source]A 5500/225 with the Apple Video System card under Mac OS 7.6.1, 8.0 or 8.1 freezes during capture and restarts with less disk space. After the software steps, check whether the I/O controller at U5 carries the silk-screen number 34S0185; if it does, replace the logic board (p. 83).
Processor fan
[edit | edit source]The processor fan, 922-3859, can be replaced on its own. It plugs into J17 on the logic board (pp. 260–261).[3] The same R363 and cache faults appear for the 6500 in its own manual.[6]
Low End Mac notes that machines with IDE hard drives do not supply SCSI termination power and rely on the external device to provide it.[5]

Source: exploded view.[3] The 225, 250 and 275 MHz logic board numbers are the same as Apple lists for the 6500/225, 6500/250 and 6500/275.[6]
