GPU
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.	Built-in video with 2 MB VRAM supports 24-bit colour through 832 × 624; 4 MB VRAM raises 1152 × 870 to 24-bit colour and is required for video mirroring
Memory type
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.	Eight 168-pin DIMM slots; Apple supports 16–512 MB total with 70 ns memory
Storage type
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.	Internal 1.44 MB floppy drive, 1 or 2 GB SCSI hard drive and 4× CD-ROM drive; Apple's Japanese configuration sheet lists the 2 GB version
Expansion slots
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	Three PCI slots; optional PC Compatibility Card

External displays
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.	Built-in video supports up to 1280 × 1024 pixels; available colour depth depends on VRAM
Keyboard and mouse
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.	–
