The Mac IIfx was released in 1990 and sold for a whopping $10,000 - $12,000, depending on configuration. The IIfx was the fastest Mac ever built at the time. The system shipped in a Mac II-style case, and could accommodate up to two Super Drives 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.
