This makes no sense commerically, I agree. If I was going to make this as

I've had idle thoughts from time to time
about building one of those and
sticking an EPROM between the outputs of that circuit and the device to be
driven, to convert the scan codes that you get to ASCII or whatever. Maybe
one of these days I'll get that particular round tuit. :-)
Why bother? AVRs and PICs are cheap and easy to work with (in
