Apple Macintosh II

Apple Macintosh II was introduced in 2 March 1987 as Apple's first modular, colour-capable Macintosh and its first model using a 68020 processor. It used a Motorola 68020 at 16 MHz with 1MB standard; expandable to 68MB. NuBus video cards allowed multiple displays and resolutions.

Six NuBus slots and separate displays transformed the Macintosh into an expandable professional workstation for publishing and graphics.
