Memory
Memory	256 MB, 512 MB or 2 GB (better)	32 MB
Storage
Storage	60 GB to 120 GB (better)	2 GB to 4 GB
CPU
CPU	Single 1 GHz, dual 1.25 GHz or dual 1.42 GHz PowerPC G4; each physical processor has 256 KB on-chip L2 cache. L3 cache is 1 MB on the single 1 GHz, 1 MB per processor on dual 1.25 GHz and 2 MB per processor on dual 1.42 GHz. Bus is 133 MHz on the single model, 167 MHz on dual models.	250 MHz PowerPC 603e with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 64-bit 50 MHz system bus. This is a distinct clock configuration from the 5500/225.
GPU
GPU	Single 1 GHz: NVIDIA GeForce4 MX with 64 MB DDR. Dual 1.25/1.42 GHz: ATI Radeon 9000 Pro with 64 MB DDR. Optional NVIDIA GeForce4 Titanium and ATI Radeon 9700 Pro, each 128 MB DDR; independent CTO options stay in details.	2 MB built-in SGRAM with hardware 2D and 3D acceleration. Exact support table gives 24-bit colour through 832 × 624, 16-bit through 1152 × 870 and 8-bit at 1280 × 1024. The Australian brochure explicitly specifies the built-in display up to 1024 × 768 with 16-bit colour, but its separate Display support subsection incorrectly repeats a 1 MB/8-bit at 832 × 624 table resembling the earlier 5400; that inconsistent subsection is not used. The exact service table confirms 2 MB SGRAM and accelerated graphics.
Memory type
Memory type	Single 1 GHz: 256 MB PC2100 DDR at 266 MHz; dual 1.25 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.42 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations retain stock drives and GPUs at base and maximum supported memory.	32 MB RAM in the exact Australian brochure and support specification, with no soldered system memory; two 168-pin DIMM sockets permit up to 128 MB. Shared Service Source specifies 60 ns or faster, 5 V buffered EDO DIMMs and supports fast-page modules too; mixing types can operate at fast-page timings.
Storage type
Storage type	Stock 60/80/120 GB 7200 rpm Ultra ATA/100 drives on 1/1.25/1.42 GHz respectively. Lower models have Combo DVD-ROM/CD-RW; top model has SuperDrive (DVD-R 4x, CD-R 16x). Four bays support two ATA/100 and two ATA/66 drives; two optical bays, one occupied. Optional 180 GB drive, SuperDrive on lower models and second Combo drive are not assumed in every configuration.	April 1997 Australian brochure specifies a graphite 32 MB/4 GB IDE/12× CD-ROM configuration. Exact support database instead lists 2 GB minimum and 24× CD-ROM. Shared Service Source documents later graphite Japanese/Australian 32 MB/4 GB/24× configurations with video input, 33.6 Kbit/s modem and Mac OS 8.0, and a US education 32 MB/24× configuration with video input, NTSC output and Ethernet. The later January 1998 family catalogue lists 2 GB and 12× or 24× drives. All retain a 1.44 MB SuperDrive floppy; optical-drive and bundle conditions are kept explicit.
Expansion slots
Expansion slots	Four open full-length 64-bit 33 MHz PCI slots and AGP 4x graphics slot.	One PCI slot for a 6.88-inch, 15 W card with a Macintosh driver, Communications Slot II for modem or Ethernet, video-input slot and optional TV/FM tuner bay. Australian brochure includes video input and lists TV tuner with infrared remote and Avid Cinema card/software as optional. The later US education configuration also supplies NTSC output.

Display type
Display type	–	Built-in noninterlaced flat-square multiple-scan CRT, 15-inch nominal tube with 325 mm diagonal viewable image (12.8 inches in the January 1998 family catalogue), 0.28 mm dot pitch and software-selectable modes from 640 × 480 to 1024 × 768. Brochure states up to 75 Hz without assigning that maximum to the highest resolution, so headline refresh remains omitted. Base tilts −5° to +15° and swivels 360°.

Front ports
Front ports	Headphone minijack and built-in speaker.	Headphone output, sound-volume and display controls; infrared receiver for the optional TV/FM remote.
Back ports
Back ports	One FireWire 800 and two FireWire 400 (15 W total), two chassis USB 1.1, Gigabit Ethernet, V.92 modem, ADC/DVI, audio line-in/out and Apple Pro Speakers minijack. Maker four-port USB total includes two ports on the keyboard. Optional AirPort Extreme 54 Mbps 802.11g card and Bluetooth 1.1 module.	ADB, external DB-25 SCSI, two RS-232/RS-422/LocalTalk/GeoPort-compatible serial ports, PlainTalk-compatible sound input and stereo output. Australian brochure includes a high-speed GeoPort modem without a published rate; later graphite service configurations specify a 33.6 Kbit/s modem. Exact support and US education service configuration list 10BASE-T, while the January 1998 maker catalogue qualifies Ethernet as configuration-dependent. Modem and Ethernet use the same communications slot; no universal Ethernet headline is assigned. Brochure supports six external SCSI devices.
External displays
External displays	Two displays in extended desktop or mirroring modes. ADC and DVI connectors with included DVI-to-VGA adapter; digital up to 1920 × 1200, analogue up to 1600 × 1200. A second ADC display needs a separately sold adapter.	January 1998 family catalogue lists NTSC TV output on some configurations; the service manual confirms NTSC output in the US education 250 MHz bundle. Australian brochure establishes built-in video input but does not establish included TV output. Computer-monitor video mirroring needs the appropriate external connector; do not treat an optional connector as included.
Speakers
Speakers	Built-in speaker; optional Apple Pro Speakers.	Built-in stereo speakers, 16-bit stereo sound input/output and SRS 3D surround processing, with rear stereo speaker output.
Microphones
Microphones	–	Built-in microphone; PlainTalk-compatible external sound input.
Keyboard and mouse
Keyboard and mouse	Apple Pro Keyboard, Apple Pro Mouse, USB keyboard extension, DVI-to-VGA adapter and modem cable.	April 1997 Australian graphite presentation includes matching keyboard, mouse and necessary cables, built-in video-in card, high-speed modem, Apple System 7.5 software and a regional productivity, reference, education and game bundle. Internet service fees are additional. TV tuner/remote and Avid Cinema are optional. Later US education and international Mac OS 8.0 bundles vary; gallery shows the beige family education configuration, unlike the graphite primary.

Size and weight detail
Size and weight detail	Maker reference 19.1 kg varies with configuration and manufacturing. Height 43.2 cm, width 22.7 cm, depth 46.8 cm.	Australian exact brochure gives 44.5 × 38.3 × 40.6 cm (height × width × depth) and 21 kg / 47 lb. Exact support dimensions and January 1998 family catalogue agree. Weight varies with installed internal devices. Shared service physical table swaps width/depth and prints inconsistent pound/kilogram weights; the exact brochure measurements are used.
Power supply
Power supply	100–125 V or 200–240 V AC, 50–60 Hz; maximum current 6.5 A at low voltage or 7.5 A at high voltage. No wattage is supplied by this sheet.	Exact support and Australian brochure specify 220 W maximum continuous, 110–240 V AC at 50–60 Hz; includes low-power sleep mode. Shared Service Source lists a separate 125 W entry and 220 W maximum for all line/load conditions. No value is treated as measured operating consumption.
Noise
Noise	–	Variable-speed fan automatically runs at the lowest speed needed to minimise noise; the processor also has a small cooling fan. No acoustic measurement is published in these sources.
In the box
In the box	Mac OS X with Classic environment rather than native Mac OS 9 boot; iLife and productivity software. Single 1 GHz and dual 1.25 GHz were available on 28 January 2003; dual 1.42 GHz was announced for the following month and subsequently reviewed. Its later availability does not change the generation’s first on-sale date.	April 1997 Australian maker brochure presents the 250 MHz graphite computer as a ready-to-use product and directs buyers to authorised resellers. Exact support later records introduction on 1 September 1997, while the Australian brochure predates that regional/configuration entry. Retail year 1997 is supported by the contemporary Australian sales brochure; exact first-sale month is unresolved. Exact support lists System 7.5.5 with Enabler 411; later shared service configurations use Mac OS 8.0.
