There are several switch makers that sell keypads that
are simply switch
arrays which you can hook up however you like. If you look at a few switch
makers' catalogs, perhaps you can find what you need and then connect the
switch matrix to match what's on the KIM. I've built memory circuits, etc,
for the KIM, but never paid much attention to the KIM itself, hence, I can't
remember anything specific about the keypad, except that it could easily
have been better, and could only have been worse with great difficulty. I
The keys on my VIM-1 are on a single large pressure sensitive
pad about 1/8 inch thick. Ruuning one's fingers across it, it's
barely noticable when you cross from one key to another. It doesn't
seem to be a keypad that would stand up to much use.
