Storage
Storage	4 GB	2 GB to 4 GB
CPU
CPU	233 or 266 MHz PowerPC G3 with 512 KB backside L2 cache at 117 or 133 MHz, a 66 MHz system bus and 64 KB L1 cache split equally between data and instructions. Supplier is not assigned without exact maker evidence.	275 MHz PowerPC 603e with integrated floating-point unit, 32 KB internal cache and 64-bit PowerPC bus. UK and Dutch exact graphite specifications give 512 KB L2 cache. Shared service describes another 275 MHz configuration with the same features as the basic 5500/225 apart from clock speed; optional 256 KB family cache does not replace the documented graphite 512 KB value.
GPU
GPU	Built-in 2D/3D graphics accelerator with 2 MB SGRAM, expandable to 6 MB using the maker-supported 4 MB SGRAM module. Exact graphics-chip revision is unpublished in the read maker datasheet, so later RAGE Pro revisions are not assumed for every unit.	2 MB SGRAM and built-in hardware acceleration for 2D QuickDraw and 3D QuickDraw 3D/RAVE. Exact archived Dutch family specifications identify ATI 3D Rage II and support 24-bit colour through 800 × 600 on the built-in CRT. Headline resolution is this explicitly documented built-in colour mode, not a fixed pixel matrix or established maximum for every colour depth. Shared service lists 640 × 480, 800 × 600 and 832 × 624 at 32 bits per pixel, 1024 × 768 and 1152 × 870 at 16 bits, and 1280 × 1024 at 8 bits; it does not establish all of these as exact regional built-in display limits.
Memory type
Memory type	32 MB SDRAM standard, up to 384 MB across three 168-pin DIMM slots. Apple Service Source specifies 3.3 V, 64-bit, 10 ns unbuffered SDRAM. Its prose about 64 MB DIMMs conflicts with its 384 MB/three 128 MB DIMM maximum; the explicit published maximum is retained. Factory BTO memory options included 64 or 96 MB.	Graphite UK and Dutch family configurations have 32 MB EDO RAM, expandable to 128 MB in two 168-pin DIMM sockets. No system RAM is soldered on the logic board. Archived exact Dutch page specifies noncomposite 5 V, 60 ns or faster EDO DIMMs with 1K or 2K refresh. Shared service also permits 5 V fast-page DIMMs and warns that mixing types can use fast-page timings. Basic service configuration has 16 MB. 4 MB ROM.
Storage type
Storage type	Both published 233 and 266 MHz base configurations have a 4 GB IDE disk, 24× maximum CD-ROM and 1.44 MB floppy drive. A 6 GB disk and 100 MB SCSI Zip drive were optional. Service Source also mentions a 2 GB disk in one table, unlike the exact base configuration datasheet; that unsupported base pairing is not assumed.	Exact graphite family configuration has a 4 GB IDE hard drive, internal 24× CD-ROM and Apple SuperDrive floppy. Shared service also documents a basic 275 MHz configuration inheriting 16 MB RAM, a 2 GB or larger drive and 12× CD-ROM from the basic 225 MHz model; the 2 GB configuration is the documented minimum, not a claimed universal shipped capacity. Optical drives and software differ between these configurations. Shared service describes the floppy as 1.4 MB; the archived Dutch page uses the same maker wording.
Expansion slots
Expansion slots	Three 7-inch PCI 2.1 slots with Macintosh drivers required; three memory slots and a PERCH I/O-card slot. Optional modem fits the I/O card. The chassis has a slide-out logic-board tray. PCI card power restrictions are three 15 W cards, two 25 W cards, or one 15 W and one 25 W card.	One 32-bit PCI 2.0 slot for a 7-inch card with Macintosh drivers; communications slot occupied by the supplied graphite modem or optional Ethernet; video-input slot and TV/FM tuner bay. Graphite family specification includes TV/FM tuner and video-input card. Avid Cinema video-editing hardware is optional and requires Apple Video System. NuBus cards are not compatible with the PCI slot.

Display type
Display type	15-inch multiple-scan colour CRT with 13.8-inch viewable diagonal and 0.28 mm dot pitch; tilt and swivel. The supported 1024 × 768 mode is analogue, not a fixed pixel matrix. Maker advertises refresh up to 85 Hz without assigning that maximum to the highest resolution, so headline refresh is omitted. Service Source specifies 16-bit colour at 1024 × 768; the datasheet uses inconsistent colour-depth labels.	Built-in 15-inch nominal colour CRT with 12.8-inch visible diagonal. Shared service specifies 0.28 mm dot pitch and shadow-mask tube. Archived exact family page states up to 85 Hz without tying this figure to a resolution; headline refresh remains omitted. Display brightness controls are on the front, and the housing uses a swivel base.
Connections
Ports
Ports	Ethernet, 3 × headphone jack	2 × headphone jack
Front ports
Front ports	–	Headphone output, sound-volume and display-brightness controls, and infrared receiver for the TV/FM remote. Front jack plus rear stereo output give the headline two output jacks; sound input is counted separately in details.
Ethernet
Ethernet	0.01 Gb/s	–
Back ports
Back ports	10BASE-T Ethernet, one ADB, one external DB-25 SCSI, two GeoPort-compatible serial ports, rear stereo audio input/output and DB-15 monitor connector. Three headphone-compatible audio outputs total: two at the front and one at the rear. No built-in USB, FireWire or AirPort support. The optional Fast Ethernet PCI card does not change the standard network figure.	ADB; external DB-25 SCSI with support for six external devices in the original Dutch family page; two RS-232/RS-422 serial ports with LocalTalk and GeoPort support in shared service; PlainTalk-compatible stereo sound input and rear stereo output. Graphite family modem supports data up to 33.6 Kbit/s, fax up to 14.4 Kbit/s, voice, answering-machine and hands-free functions; data rate depends on connection and provider. Archived page lists MNP4, V.42, MNP5 and V.42bis. Ethernet is a communications-slot option, not universally fitted. No USB or FireWire.
External displays
External displays	DB-15 external monitor connector documented by the exact datasheet and rear service diagram; the current support summary instead labels video as none. Display mirroring is described by the contemporary Washington Apple Pi test, not an assumed extended desktop.	Computer-monitor video mirroring requires the optional external-video connector kit. Shared service supports mirroring at 640 × 480, 800 × 600 or 832 × 624; this does not establish an independent extended desktop. Avid Cinema provides optional PAL/NTSC video editing and output and requires the video-input system. Included TV/FM reception is not proof of included TV output.
Speakers
Speakers	Built-in stereo speakers; 16-bit stereo audio input/output at 22.05 or 44.1 kHz	Two built-in stereo speakers and 16-bit stereo sound input/output, with SRS surround-sound enhancement. Shared service supports recording at 11, 22 or 44 kHz. Front headphone and rear speaker outputs are separate.
Microphones
Microphones	Built-in microphone	Built-in microphone plus external sound-input port supporting PlainTalk microphones. Shared service explicitly excludes the earlier Omni microphone and attenuated RCA adapter.
Keyboard and mouse
Keyboard and mouse	AppleDesign Keyboard and ADB Mouse II	Exact archived Dutch ordering page identifies graphite Family Macintosh M6183 with keyboard, mouse, cables and model-specific software. Original UK Christmas 1997 brochure shows the graphite computer with matching keyboard and mouse, with TV/FM tuner and video-in listed in its 275 MHz specification. The screen artwork is original maker photography; it is not a clean unlit-screen alternative.

Size and weight detail
Size and weight detail	Headline dimensions and 26.8 kg weight follow the exact May 1998 maker datasheet. Apple Service Source gives 498 × 402 × 450 mm and 27 kg with inconsistent inch conversions; the current support summary gives 19.92 × 16.08 × 18 inches and 59.5 lb. Weight varies with installed devices.	Exact archived Dutch family page gives 40.6 × 19.8 × 42.8 cm and 20.2 kg, values resembling the companion tower rather than the pictured all-in-one. Shared service gives 445 mm height but swaps the family width/depth compared with other original all-in-one brochures, and prints internally inconsistent 17/19 lb versus 21.15 kg weights. These unresolved exact-model measurement conflicts are not promoted into headline weight or dimensions, and sibling-model measurements are not substituted.
Power supply
Power supply	Automatically configured 90–264 V AC, 50–60 Hz, single phase	Archived exact Dutch family specifications give 220 W maximum continuous input, with regional 200–240 or 100–125 V AC at 47–63 Hz and energy-saving sleep. Shared service gives 100–240 V AC at 47–63 Hz, a separate 125 W entry and 220 W maximum for all line/load conditions. These qualified ratings are not measured operating consumption.
Noise
Noise	–	Shared service describes a variable-speed enclosure fan and separate processor cooling fan, without a measured acoustic figure.
Power use
Power use	Maximum continuous electrical input 300 W; Service Source separately lists 200 W peak output, which is not acoustic output	–
In the box
In the box	Mac OS 8.1 in the contemporary datasheet and Service Source; the current archived support summary instead gives original system software 8.0. The model was offered for the education market. Apple support labels introduction as 3 April 1998; the dated May 1998 datasheet describes currently available configurations and BTO ordering from 6 May. An exact first retail delivery date is not established, so released is omitted rather than substituting introduction or BTO dates. The 266 MHz base variant adds audio/video I/O plus Avid Cinema and QuickTime 3 Pro; the 233 MHz base is audio I/O only. Optional AV hardware supports composite and S-video inputs/outputs with mode restrictions in Service Source.	Shared service graphite configuration includes Mac OS 8.0. Original UK Christmas brochure describes purchase between 1 November and 31 December 1997 for a software offer; exact Dutch product ordering page is dated September 1997 and lists 275 MHz M6183. These establish sale in 1997; actual first-sale month or day remains unresolved. UK software includes Apple Magic Collection, Actua Soccer, Kai's Power Goo and multimedia reference titles; promotional software is not another hardware generation. Product resource is the original Dutch Apple family page covering exact 225/275 configurations; the support resource is the current official Earlier Power Mac family document index in English (Macau region), which has no exact 275 MHz entry. No exact surviving English maker support specification record or user guide was recovered.
