Storage
Storage	60 GB to 120 GB (better)	700 MB
CPU
CPU	Dual 867 MHz, dual 1 GHz or dual 1.25 GHz PowerPC G4 processors; each physical processor has 256 KB on-chip L2 cache. 867 MHz and 1 GHz have 1 MB DDR SRAM L3 per processor; 1.25 GHz has 2 MB. System bus 133 MHz on dual 867, 167 MHz on dual 1/1.25 GHz. CPU count describes physical processors; supplier is not inferred.	100 MHz PowerPC 601 with integrated floating-point unit, 32 KB L1 cache, 256 KB L2 cache and 33.3 MHz system bus; 4 MB ROM
GPU
GPU	Dual 867 MHz: NVIDIA GeForce4 MX 32 MB DDR. Dual 1/1.25 GHz: ATI Radeon 9000 Pro 64 MB DDR. Optional NVIDIA GeForce4 Ti 128 MB; independent CTO options are not expanded into unsupported stock combinations.	Power Macintosh video card with 2 MB VRAM, expandable to 4 MB using four 512 KB SIMMs; separate built-in DRAM video uses system memory. This is the non-AV model, without the AV card's S-video connections.
Memory type
Memory type	Dual 867 MHz: 256 MB PC2100 DDR SDRAM at 266 MHz. Dual 1 GHz: 256 MB PC2700 DDR at 333 MHz; dual 1.25 GHz: 512 MB PC2700. Four DIMM slots support up to 2 GB. Configurations preserve stock processor/drive/graphics ties at base and maximum memory.	Apple's Japanese bundle has 16 MB including 8 MB soldered to the logic board; eight 72-pin noncomposite 80 ns SIMM sockets accept matched pairs, up to 264 MB total. Apple Service Source also lists an 8 MB configuration.
Storage type
Storage type	60/80/120 GB 7200 rpm Ultra ATA/100 stock drives respectively. Dual 867 MHz has Combo DVD-ROM/CD-RW (CD-R 16x); faster models SuperDrive (DVD-R 2x, CD-R 8x). Four hard-drive bays support two ATA/100 and two ATA/66 drives, or up to four SCSI drives with a separately sold PCI card. Two optical bays, one occupied; optional second Combo drive. Maker optional storage choices remain in details rather than assumed CPU cross-pairs.	Japanese bundle has a 700 MB internal SCSI hard drive, 1.44 MB floppy and internal 2× AppleCD 300i Plus CD-ROM. The exact-model service table also lists a 1 GB hard-drive option; CD-ROM inclusion varies by configuration.
Expansion slots
Expansion slots	Four open full-length 64-bit 33 MHz PCI slots and dedicated AGP 4x graphics slot.	Three NuBus slots and one processor-direct slot occupied by the video card; fitting an optional AV card replaces that video card rather than adding another card alongside it

Optional 11 Mbps AirPort 802.11b card. Bluetooth is a separately listed adapter, not built-in. No FireWire 800 in this 2002 generation.	ADB, external DB-25 SCSI, two LocalTalk/GeoPort serial ports, AAUI-15 Ethernet requiring a transceiver, HDI-45 and DB-15 monitor ports, and 16-bit stereo audio input and output
External displays
External displays	Two displays in extended desktop or mirroring modes; ADC and DVI with included DVI-to-VGA adapter. Connecting two ADC displays requires a separately sold DVI-to-ADC adapter.	DRAM HDI-45 and VRAM DB-15 video outputs; 2 MB VRAM supports 24-bit colour at 640 × 480 and 832 × 624, or 16-bit colour at 1024 × 768 and 1152 × 870. Expanding VRAM to 4 MB supports 24-bit colour at the latter resolutions.
Speakers
Speakers	Built-in speaker; optional Apple Pro Speakers.	–
Keyboard and mouse
Keyboard and mouse	Apple Pro Keyboard, optical Apple Pro Mouse, DVI-to-VGA adapter and modem cable.	Japanese bundle includes Apple Desktop Bus Mouse II; keyboard and monitor are separate. The catalogue photograph shows a shared 8100/100 and 8100/110 setup with external monitor, keyboard and mouse.

Size and weight detail
Size and weight detail	Exact maker reference weight 19.1 kg varies with configuration and manufacturing process; height 43.2, width 22.7, depth 46.8 cm. These published dimensions differ slightly from earlier G4 sheets and are retained.	Japanese exact-model page publishes 360 × 196 × 396 mm and 11.3 kg, with weight varying by installed drives. The English support sheet lists 14 × 7.7 × 15.75 inches and 25.3 lb; Service Source lists the same metric dimensions but 11.5 kg. The April 1995 catalogue lists 361 × 226 × 406 mm and 11.4 kg; those conflicting catalogue measurements are not used for the headline dimensions.
Power supply
Power supply	100–125 V AC or 200–240 V AC, 50–60 Hz. Maximum current 6.5 A at low voltage or 7.5 A at high voltage; maker publishes no maximum wattage here.	Automatically configured 100–240 V AC, 50–60 Hz; Service Source distinguishes 298 W maximum continuous and 453 W peak input, excluding the monitor, from 200 W continuous DC output. Apple's support sheet labels 200 W as maximum watts.
In the box
In the box	Mac OS X 10.2 Jaguar as default startup system, plus bootable Mac OS 9.2.2; iMovie, iPhoto, iTunes and iDVD for SuperDrive. Maker August 13 release says dual 867/1 GHz available that week, so first sale uses August month precision. Actual dual-1.25 GHz shipping confirmed 18 September. January 2003 FireWire 800 models and June 2003 reissue are separate generations.	Japanese bundle includes power cable, KanjiTalk 7.5 CD-ROM and documentation. Apple lists introduction on 3 January 1995; the April 1995 maker catalogue establishes a current offering that year, without resolving the first-sale month.
