Macintosh IIfx

Introduced: March 1990
Terminated: April 1992

Description

The Macintosh IIfx had a clock rate of 40MHz, which was very impressive at that time.  It also had 32K in a level two cache and six NuBus expansion slots.  Application-specific integrated circuits (ASICs) and coprocessors made for even faster speeds.  The IIfx had eight RAM slots that meant the 4MB could be expanded to 128MB.  The Macintosh IIfx could hold up to two Super Drives along with an internal hard drive. 

History

The Macintosh IIfx was the high-end model of its day with a price range of between $10,000-12,000.  Everything in the computer was designed for maximum speed and performance.  Software had to be written especially for the IIfx that would take advantage of the speed capabilities.

  • One of the disadvantages on heating with wood pellets has been that unlike firewood, home owners couldn’t go out making their pellet cooler. This really is all changing now that home owners and smaller businesses are making pellets with small scale pellet mills.
