Apple Macintosh IIx

Apple Macintosh IIx was introduced in 19 September 1988 and updated the six-slot Macintosh II with a 68030 processor and SuperDrive. It used a Motorola 68030 at 16 MHz with 1MB standard; expandable to 128MB. 68030 integrated a memory-management unit for advanced operating systems.

The IIx established the 68030 as Apple's professional Macintosh processor while retaining maximum NuBus expansion.

Notable Features

• 68030 integrated a memory-management unit for advanced operating systems.
• 1.44MB SuperDrive exchanged disks with MS-DOS systems.
• Six NuBus slots preserved workstation-level expansion.

Historical Significance

• The IIx established the 68030 as Apple's professional Macintosh processor while retaining maximum NuBus expansion.
• Its place in the range reflects Apple's progression from the original compact Macintosh toward broader professional, educational and portable markets.

Collector’s Notes

• Large logic boards are vulnerable to battery leakage and ageing surface-mount capacitors
• Original keyboards, mice, storage devices and model-specific accessories help document a complete period configuration.
