The Macintosh IIfx is a personal computer designed, manufactured and sold by Apple Computer from March 1990 to April 1992. At introduction it cost from US$9,000 to US$12,000, depending on configuration, and it was the fastest Macintosh available at the time.

The Macintosh IIfx is the fastest model in the Macintosh II series partly due to then-superfast RAM that was unique to the IIfx, a level 2 cache, and advanced hardware that allowed some applications to be optimized explicitly for speed.

Macintosh IIx: Apple’s flagship gains a better CPU, FPU, and floppy drive, Dan Knight, Mac Musings, 2007.09.19. 20 years ago Apple improved the Mac II by using a Motorola 68030 CPU with the new 68882 FPU. And to top it off, the IIx was the first Mac that could read DOS disks with its internal drive.

The IIfx was (is still?) a high powered machine with many hardware additions to create a very powerful system. The CPU was a 32-bit 68030 at 40 MHz that was supported by a 40 MHz 68882 FPU, 40 MHz bus speed (pretty impressive for 1990), 32K L2 cache, and custom I/O Processors for the SCSI, ADB, and serial ports (in part because the IOPs had 32 ...

May 16, 2015 · A quarter of a century ago this was the most powerful Macintosh of the series II: it was powered by a 68030 processor at 40MHz, outperformed only by the following Quadra computers with a 68040 processor. To create the opening image, I shot two pictures on a tripod, with and without the top cover.

Introduced in 1990, Macintosh IIfx was the fastest Mac in its time, outperformed by later (late 1991) Quadra lines containing Motorola 68040 processor. IIfx has earlier 68030 CPU, but it is clocked to 40MHz, while early Quadras ran on 25 or 33MHz.

Released in March 1990, The Mac IIfx was the fastest Mac ever built at the time. The IIfx shipped in a Mac II-style case, and could accommodate up to two Super Drives and and internal SCSI hard disk. Dubbed "Wicked Fast" by the press, the IIfx also contained a number of proprietary ASICs designed to speed up the machine further.

Apple took the speed issue by the horns in March 1990, rolling out the 40 MHz Macintosh IIfx along with the 8•24GC accelerated video card. The DOS world was pretty content with 33 MHz computers with a 32 KB (or sometimes larger) Level 2 (L2) cache and often a memory bus running at half of CPU speed.
