Possibly, but I know about that. I was referring mainly to the types
of keyboard commonly seen in dump/second-hand shops today. Because,
face it, if you have them already, you know about it, and if you don't
have them, that's where you'd go to buy it :). I once bought a few
130 column 9-pin dot matrix serial terminals. 1*1 meter, keyboard,
printer, and heavy as hell. Those must've been 70's or earlier, I
think. They already had the large PCB with copper islands approack in
the keyboard :(. Not discrete keys, at least in the sense that they
were usable alone. Actually, my current keyboard is at least 15 years
old, and uses that same technique. (ObAside: I love that keyboard.
Bought it second hand for $10 6 or 7 years ago, cleaned it, loved it,
never stopped using it.)
