The “wicked fast” Macintosh IIfx was not only the fastest Macintosh to date when released in March 1990, at 40 MHz it would also be the fastest Motorola 68030-powered machine Apple ever made. Combined with unique, 64-pin, dual-ported RAM SIMMs (up to 128 MB), MOS 6502-powered serial and sound processors, and support for up to six displays, the IIfx was truly a powerhouse machine. It was to be the last of the “big-box” Macintosh II models with a full six NuBus slots.

The Macintosh IIfx featured a 40 MHz Motorola 68030 processor with 32 KB Level 2 cache, 68882 FPU, 4 MB 640-pin RAM, 80 MB or 160 MB SCSI hard disk drive, 1.44 MB “SuperDrive” floppy disk drive (with an option for two), and a host of serial and ADB ports in back.

This IIfx machine features 8 MB RAM, a RasterOps 24sTV video card, Farallon 10bT network adapter, an internal 160 MB SCSI hard disk drive and dual 1.44 “SuperDrives”.
