Macintosh Quadra 840AV

The Macintosh Quadra 840AV was most powerful Ordinateur Apple based on the family of Processeur Motorola 68000.

Named during its development Cyclone , this machine was properly revolutionist at the time of his exit. It integrated characteristics hitherto unknown on microcomputers. The most outstanding characteristics were the recognition and the voice synthesis, the audio and video capture thanks to a DSP AT&T 3210 to 67 integrated MHz.

Its marketing began the July 29th 1993 at the cost of 4200 $ to be completed the July 18th 1994.
