 Page under construction
During the 70's and 80's, Casio brought a lot of interesting innovations to the market. Most of them, however, met limited success, as the market for this kind of machines was not that wide at the time.
One of the things Casio experimented with in the 80's was sensitive surfaces technologies. The PF-8000 is one the first application of these experiments. Just like other machines from that time, the PF-8000 uses a sensitive keyboard. What's quite different from the others, tho, is that the sensitive area is not only used for keystroke detection. Casio introduced an intersting idea : on the PF-8000 data input can be achieve simply by "drawing" character with a fingertip on the sensitive area.
As of writing this, i have not tested the method yet, but i'm glad i've found the little device to add to my collection. In several websites, i've noticed the PF-8000 is sometimes mistaken for the IF-8000. The IF-8000, also from Casio, is also a pionneer in data input using a sensitive surface, and also bears a "8000" reference. They are two very different machines...
The IF-8000 uses a large, graphical touch-screen display whereas the PF-8000 is much simpler in design, but offers characters recognitions, something the IF-8000 doesn't.
As a matter of fact, the PF-8000 is heavily based on character recognition. As this feature requires an important computing power, the PF-8000 uses a powerful chip and was tested much faster than most of it's competitors, just because it needs the power to properly handle character recognition.
Maybe for cost reasons, the rest of the machine is thus simpler : no graphic screen, and no touch screen of course.
After having presented the first character recognition system, then the first sensitive-screen system, one could have expected Casio would pionneer the first sensitive-screen character recognition system... well Casio did not. It's not clear to me yet which machine was actually the first one to offer such features, but it was not from Casio.
