In the very early 80's. Steve Ciarcia (Micromint) designed an Apple
II 'camera' that used this concept... it had a the chip behind a
common c-mount TV lens, an interface board, and software to manage
the image, do simple dithering, print the images, etc.
The one I owned is now on it's way to Hans Franke... so he might
be able to report on it if he gets it up and running.
