CPUNominal 16 MHz 68020 with 68881 floating-point coprocessor and optional 68851 paged memory management unit; 0.25 KB L1 cache, no L2 cache or second processor25 MHz Motorola 68030 with integrated memory management and 68882 floating-point coprocessor; 0.5 KB L1 cache
GPUNo integrated video output; one NuBus video card is needed for a display. Apple offered colour or monochrome cards and monitors separatelyBuilt-in video uses 64–320 KB of system RAM and supports 8-bit colour at 512 × 384 or 640 × 480; NuBus graphics cards can also be fitted
Memory typeEight 30-pin SIMM slots in banks of four, 120 ns or faster; Apple lists 1–20 MB across revisions, using 256 KB, 1 MB or 4 MB modules. A 4 MB module cannot go in Bank A without the SuperDrive upgrade; 256 KB ROMEight 30-pin SIMM slots in two banks of four; 80 ns fast-page memory, 1–128 MB supported by Apple; 512 KB ROM
Storage typeOne or two 800 KB floppy drives; Apple lists 40–80 MB internal SCSI hard drives. The two configurations represent the independently documented 1 MB floppy-only and 1 MB/40 MB factory systems; no RAM and 80 MB drive pairing inferredInternal 1.44 MB floppy drive and space for one 40 or 80 MB SCSI hard drive; Low End Mac documents an original floppy-only offering and a 40 MB hard-drive configuration
Expansion slotsSix 32-bit NuBus slots, one occupied when a display video card is installedThree NuBus slots plus a cache/processor-direct connector; Apple's later support sheet lists 32 KB L2 cache, while its original developer note calls the cache card optional

External displaysRequires a separately purchased NuBus video card; supported resolution and colour depth depend on that card, so no fixed display capability is assertedBuilt-in video supports Apple's 12-inch monochrome, 13-inch RGB and 15-inch portrait displays; other displays require a compatible NuBus card
