Product links

Processor: PowerPC 601 100 MHz (Power Macintosh 8100/100)
CPU cores: 1
Memory: 16 MB
Storage: 700 MB
CPU: 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: 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: 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: 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: 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

Ports: Ethernet
Back ports: 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: 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.
Keyboard and mouse: 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.

Type: Tower
Weight: 11.3 kg
Width × depth × height: 196 × 396 × 360 mm
Operating system: macOS
Size and weight detail: 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: 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: 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.
