The Macintosh IIx was introduced by Apple Computer in 1988 as an incremental update of the original Macintosh II model. It replaced the 16 MHz Motorola 68020 CPU and 68881 FPU of the II with a 68030 CPU and 68882 FPU running at the same clock speed; and the 800 KB floppy drive with the 1.44 MB SuperDrive (the first Mac to have this feature). The initial price of the IIx was US$7,769 (equivalent to $15,733 in 2016) or US$9,369 (equivalent to $18,973 in 2016) for a version with the 40 MB hard drive.[1]
The Mac IIx included 0.25 KiB of L1 instruction CPU cache, 0.25 KiB of L1 data cache, a 16 MHz bus (1:1 with CPU speed), and supported up to System 7.5.5.
The IIx was the second of three Macintosh models to use this case allowing dual floppy drives and 6 NuBus slots; the last model was the Macintosh IIfx. Apple's nomenclature of the time used the "x" to indicate the presence of the '030 CPU as used in the Macintosh IIcx and IIvx.
Support and spare parts for the IIx were discontinued on August 31, 1998.
