CPU
CPU	Original 300, 350 and 400 MHz PowerPC G3 range; later 350, 400 and 450 MHz. The 300 MHz has 512 KB backside L2 cache; faster models have 1 MB, all at half processor clock. 100 MHz system bus, integrated FPU, 32 KB each instruction/data L1 cache. Manufacturer supplier is not assigned without exact fitted-chip evidence.	Stock single 1.25 GHz PowerPC G4 with 256 KB L2 cache and 1 MB L3 cache. Contemporary Macworld reporting of Apple Store configurations also documents dual 1.25 GHz processors, each with 2 MB L3; this custom build is labelled in configuration details rather than presented as a second stock base.
GPU
GPU	ATI RAGE 128 GL PCI card with 16 MB SDRAM, installed in the dedicated 66 MHz PCI slot. Supports QuickDraw 3D RAVE and OpenGL; DVD configurations add a hardware MPEG-2 decoder module.	Stock ATI Radeon 9000 Pro with 64 MB DDR in an AGP 4x slot. Macworld also documents a custom dual-processor build with NVIDIA GeForce4 Titanium; that build has other upgrades and is not treated as a freely interchangeable stock configuration.
Memory type
Memory type	Four 168-pin 3.3 V unbuffered PC100 SDRAM slots; maker maximum 1 GB. Factory memory of 64 or 128 MB stays tied to each configuration.	Stock 256 MB PC2700 DDR333; four DIMM slots, maximum 2 GB. The single-processor configurations retain the stock drive and graphics at base and maximum memory. The documented dual-processor custom base has 256 MB.
Storage type
Storage type	Apple’s Japanese model list separates original factory pairs: 300 MHz/64 MB/6 GB ATA/CD (M6670); 350 MHz/64 MB/6 GB ATA/DVD (M6668); 350 MHz/128 MB/12 GB ATA/CD/Zip (M6666); 400 MHz/128 MB/9 GB Ultra2 Wide SCSI/CD (M6665). Later pairs: 350 MHz/64 MB/6 GB ATA/CD (M7556); 400 MHz/64 MB/6 GB ATA/DVD (M7555); 400 MHz/128 MB/12 GB ATA/CD/Zip (M7554); 450 MHz/128 MB/9 GB Ultra2 Wide SCSI/CD (M7553). Service Source distinguishes original 24x or 32x CD drives; current revised sheet gives 32x CD and 5x DVD. Optional BTO combinations are not multiplied into unverified configurations.	Stock 80 GB 7200 rpm Ultra ATA/100 hard drive; up to four internal drives. Tray-loading Combo drive reads DVD at 8x and CD at 32x, writes CD-R at 16x and CD-RW at 10x. Macworld documents a dual 1.25 GHz custom base with 80 GB, Combo drive and Radeon 9000 Pro, and a separate upgraded build with 2 GB RAM, two 160 GB drives, SuperDrive and GeForce4 Titanium. The two-drive build is described here without flattening its drives into a single capacity.
Expansion slots
Expansion slots	Four PCI slots: three 64-bit 33 MHz slots and one 32-bit 66 MHz slot occupied by graphics. Two extra internal hard-drive expansion bays; SCSI configurations use a PCI controller card.	Four PCI slots and an occupied AGP 4x graphics slot.

Back ports
Back ports	Two 12 Mbps USB ports, two FireWire 400 ports, one ADB port, 10/100BASE-T Ethernet, VGA and stereo audio input/output. Optional 56K modem is separate. Keyboard’s two USB ports excluded from chassis count. Current maker table corrects the developer note: ADB total current maximum is 500 mA, not 100 mA.	Two USB 1.1, two FireWire 400, Gigabit Ethernet with Auto-MDIX, ADC and DVI display connectors, audio line-in/out and Apple Pro Speakers connection. The maker lists a V.92 modem. Optional original AirPort; the contemporary Apple-spokesman report confirms no AirPort Extreme, internal Bluetooth or FireWire 800.

In the box
In the box	Mac OS 8.5.1 originally; later stock has Mac OS 8.6. Apple’s 5 January 1999 release says the new range arrives on the market; contemporary January demonstration coverage says Apple is now shipping. Month precision retained, no inferred exact first-delivery day. Server G3 bundled configurations are excluded.	Mac OS X 10.2.4 and bootable Mac OS 9.2.2, install/restore DVD and Apple Hardware Test. First sale uses the 23 June 2003 Macworld report that these models were for sale at Apple’s online store; a 29 June report quotes an Apple spokesman confirming manufacture and sale. The first day is contemporary Apple Store reporting rather than a retained maker launch notice.
