Macintosh IIfx
The Macintosh IIfx is the fastest of the II line and shipped with a 40MHz Motorola 68030 processor.
General Information[edit]
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. These required software written specifically for the IIfx to run at top speed, but either way it was an extremely powerful machine. It sold for $10,000 - $12,000, depending on configuration.
The floppy drive, ADB and serial ports on the Macintosh IIfx are controlled by a pair of 10MHz 6502 processors.
Codenames: Stealth, Blackbird, F-16. The IIfx was discontinued in April 1992. Originally shipped with system software 6.0.5.
CPU[edit]
The Macintosh IIfx uses the Motorola 68030 processor clocked at 40MHz, making it the fastest '030 based Macintosh from the factory. A Motorola 68882 math co-processor is included.
Memory[edit]
The IIfx uses unique memory which uses 64 pins, not shared by any other Macintosh model.
