Page under construction
The PTC-500 was released in 1990 in Japan. It's certainly one of the earliest Sony portable computers, if not the earliest, and it's quite in line with what R&D departments were working on back then : bring the power of graphic interfaces computers to portable devices.
It also pionners a feature that will make the Newton famous a few years later : handwritting recognition. If it may seem the Newton came out of nowhere and introduced revolutionnary ideas, it appears that most of the features the Newton is famous for were actually experimented by quite a number of earlier devices; mostly in Japan as far as i could say.
The Sony PTC lineup (that saw at least a PTC-300 model and a PTC-310 model released after the original PTC-500) was actually not one of a kind in Japan in the early 1990's. Kyocera also had a similar platform available (check the Refalo in my collection) years ahead the Newton release; and other manufacturers like Nec or Fujitsu were working on competing devices.
I have not tested my PTC-500, and i'm afraid it is not in working condition just like most of the PTC i saw on sale. It is already quite interesting to watch even when it's not working! ^_^
Many details about the PTC-500 are now quite dated. The stylus, for instance, is linked to the body by a cable that is apparently necessary for the touch-screen to run. The speaker is also oddly shaped and quite reminiscent of old vocal modems! As a matter of fact, i also own a modem extension for the PTC-500 (no picture yet), and it actually is one of those bulky audio modems like the one in the Wargame movie.
