Macintosh IIx

Introduced: September 1988
Terminated: October 1990

Description

The most important change in the Macintosh IIx was the increased power of the CPU and FPU. The Motorola 68030 processor was capable of speeds of 16 MHz.  The 800KB floppy drive was a SuperDrive capable of handling the 1.44MB high-density disks.

Like the original Macintosh II, the Macintosh IIx was sold as a separate component rather than as an all-in-one device.  It was expandable and could be used with a number of Apple or third-party products.

History

The Macintosh IIx updated on the original Macintosh II line, offering an upgradable, high-end option to Macintosh users.  At $7800, it did not come cheap.  However, like the earlier model, the user selected their own monitor, meaning that the entire system did not need to be replaced.
