Code named "Cyclone", the 840av was truly a revolutionary machine! It supported many never before seen features such as speech recognition, the ability to talk, sound digitizing and a new digital signal processor that allowed the 840av to process huge streams of sound and video information. Unfortunately, the 840av did not work with many standard Mac monitors. For some, you could get a special cable that worked with the AV; others couldn't be made to work at all! Current used market value of a 8/230 configuration: $775
