Performance

Processor: PowerPC G3 233 MHz (Power Macintosh G3 Desktop) or PowerPC G3 266 MHz (Power Macintosh G3 Desktop)
CPU cores: 1
Graphics: Built-in graphics accelerator (2 MB SGRAM; revision unpublished)
Memory: 32 MB
Storage: 4 GB
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.
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 Exact graphics-chip revision is unpublished in the read maker datasheet, so later RAGE Pro revisions are not assumed for every unit.
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.
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.
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.

Display

Screen size: 15″
Resolution: 1024 × 768
Panel: CRT
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.

Connections

Ports: Ethernet, 3 × headphone jack
Ethernet: 0.01 Gb/s
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.
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.
Speakers: Built-in stereo speakers; 16-bit stereo audio input/output at 22.05 or 44.1 kHz
Microphones: Built-in microphone
Keyboard and mouse: AppleDesign Keyboard and ADB Mouse II

Design and power

Type: All-in-one
Weight: 26.8 kg
Width × depth × height: 409 × 457 × 505 mm
Operating system: macOS
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.
Power supply: Automatically configured 90–264 V AC, 50–60 Hz, single phase
Power use: Maximum continuous electrical input 300 W; Service Source separately lists 200 W peak output, which is not acoustic output
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.
