Macintosh IIx

The Macintosh IIx was introduced by Apple in 1988 as an incremental update of the original Macintosh II model. It replaced the Motorola 68020 processor of the II with a 16 MHz 68030 processor (running at the same clock speed), and the 800K floppy drive with the SuperDrive. The initial price of the IIx was $7,800 USD or $9,300 for a version with the 40MB hard disk drive.

The IIx was the second of three Macintosh models to built in this case with the 6 NuBus slots; the last was the Macintosh IIfx.

Mac OS 7.6 is incompatible with this Macintosh IIx unless you have a Motorola 68030 32-bit processor.

Apple's codenames for the IIx included "Spock" and "Stratos". Support and spare parts for the IIx were discontinued on August 31 1998.
