Released May 1987

Apple's first modular colour-capable Macintosh has a separate display, six NuBus expansion slots and a 16 MHz 68020 processor.

Specifications

Processor: 68020 16 MHz (Macintosh II)
CPU cores: 1
Memory: 1 MB
Storage: 40 MB
CPU: Nominal 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 processor
GPU: No integrated video output; one NuBus video card is needed for a display. Apple offered colour or monochrome cards and monitors separately
Memory type: Eight 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 ROM
Storage type: One 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 inferred
Expansion slots: Six 32-bit NuBus slots, one occupied when a display video card is installed

Ports: Headphone jack
Back ports: Two Apple Desktop Bus ports, DB-25 SCSI, printer and modem serial ports and stereo sound output; no built-in Ethernet or video socket
External displays: Requires a separately purchased NuBus video card; supported resolution and colour depth depend on that card, so no fixed display capability is asserted
Speakers: Built-in speaker and stereo 8-bit sound output

Type: Compact
Weight: 10.9 kg
Width × depth × height: 475 × 366 × 140 mm
Operating system: macOS
Size and weight detail: Apple's reference dimensions are 5.5 × 18.7 × 14.4 inches and 24 lb; metric fields are rounded conversions
Power supply: Maximum 230 W; 90–270 V AC, 48–62 Hz, 1.9 A; soft power and monitor power pass-through
In the box: Original System Software 2.0. Apple introduced the Macintosh II on 2 March 1987; contemporary reporting expected May shipments, and Wikipedia cites an 8 May Wall Street Journal report of their start
