Power Macintosh 4400
The Power Macintosh 4400 is a desktop Macintosh with a PowerPC 603e processor, sold from November 1996 as the 160 MHz 4400/160 and from February 1997 as the 4400/200. Apple's service manual describes it as "an entry-level computer", and names the same machine the Power Macintosh 7220/200 in the Far East.[1] Wikipedia describes it as built from off-the-shelf parts, including an IDE hard drive and an ATX-style power supply, around a "Tanzania" logic board that Apple had designed but used before only in Mac OS clones.[2] Low End Mac gives the code names Cupid and Tanzania and notes that the 4400 is the only Power Macintosh with its floppy drive on the left.[3]
Models
[edit | edit source]| Model | Introduced (Apple) | Clock | RAM range | Hard drive | Notes |
|---|---|---|---|---|---|
| 4400/160 | 7 November 1996 | 160 MHz | 16–96 MB | 1.2 GB | Three PCI slots; no Ethernet; optional L2 cache; "not sold in the U.S." |
| 4400/200 | 17 February 1997 | 200 MHz | 16–160 MB | 2 GB | Two PCI slots and a communications slot II; 10BASE-T Ethernet |
| 4400/200 PC Compatible | 4 April 1997 | 200 MHz | 32–160 MB | 2 GB | Cyrix 6x86 PC Compatibility Card in the long PCI slot; 12× CD-ROM; Windows 95 included |
| 7220/200 | 17 February 1997 | 200 MHz | 16–160 MB | 2 GB | The 4400/200 under its Far East name; "not sold in the U.S." |
Sources: Apple's specification pages for each model.[4][5][6][7] The service manual lists the 4400/160 as "Europe Only" and the 7220/200 and 7220/200 PC for the Far East (p. 1); Low End Mac says the 7220 was the Australian name.[1][3]
The 4400/200 differs from the 4400/160 in four ways according to Apple: a communications slot II on the PCI adapter card, two PCI slots in place of three, the 200 MHz clock and a 160 MB memory ceiling (p. 4).[1]
Hardware

| RAM | No RAM on the logic board. Three slots for 64-bit, 168-pin, 3.3 V unbuffered EDO DIMMs, 60 ns or faster. 4400/160: 16 MB standard, each slot up to a 32 MB bank, 96 MB maximum. 4400/200 and 7220/200: 32 MB standard, first slot up to 32 MB and the other two up to 64 MB each, 160 MB maximum. Slot 1 takes single-bank DIMMs only (pp. 13–14, 23) |

Source: the service manual, at the pages given.[1] Apple's specification pages give 150 W maximum and 3 A for the supply, where the manual gives 200 W; the pages also list 256K of L2 cache as standard on the 4400/200, where the manual calls it optional.[5] The manual's 24 lb and 9.5 kg do not agree (24 lb is about 10.9 kg). Low End Mac gives 2 MB of video memory for the 4400/200, against Apple's 1 MB EDO DIMM.[3]

Voltage switch
[edit | edit source]The supply is switched by hand. Set it with a screwdriver to "115" for 100–130 V or "230" for 200–230 V; Apple says it "must be set correctly to avoid damaging the computer", and the manual prints a table of mains voltages by country. Setting the switch does not change the monitor's supply (pp. 5–8).[1] Wikipedia quotes MacWEEK's review on the point: Apple had "abandoned automatic switching in the power supply".[2]
Key commands and power
[edit | edit source]The 4400 has no programmer's switches. Hold the keyboard Power key and press Command for interrupt, or Control-Command for reset, for at least a second. The machine turns on from the keyboard Power key or from the power button on the front (p. 9).[1]
Clock battery
[edit | edit source]Apple's specification pages give the battery as 4.5 V alkaline. It sits on a hook-and-loop base with a plug-in lead, and Apple's test is to replace it below 3.0 V on the 10 V DC range (pp. 121–124). On 4400s sold in Germany the battery is in a different place under the cache card, and Apple's procedure ends by pressing the reset switch on the logic board (pp. 128–130).[1][5] Low End Mac warns that Tanzania-based machines "will not boot with a dead PRAM battery", so change the battery before condemning the power supply of a dead 4400.[3] Alkaline leakage is caustic; see Battery Explosion, Capacitor or Corrosion Damage.
Known faults
[edit | edit source]Apple's symptom charts include two faults it says affect only early European 4400s (pp. 40, 44):[1]
- After a restart, two monitors used for video mirroring show black or grey. Unplug the monitor on the PCI video card and restart, or turn mirroring off before shutting down and back on after start-up.
- The hard drive is not recognised because of an IDE bus termination problem. Make sure the CD-ROM interface cable is connected, then check the hard drive cables.
The front power button and LED wires run under the floppy/CD-ROM carrier and are "easily cut" when the carrier slides across them; Apple's chart for a machine that starts from the keyboard but not the front button begins with checking that cable for cuts (pp. 37–38, 76).[1] The full charts are on Power Macintosh 4400 Troubleshooting.
