Yep, that is what I do. The clicky ones tend to have a full length circuit board and you can go right to the letters you want with no fuss.

Or I do the OLD, OLD IBM keyboard that has the detachable cord. It basically has a freaking encoder inside it to begin with. You won't get to pick your letters all easy, but it is REAL easy to do.

If you get your self a "keytronic" keyboard I have the matrix all mapped and even the circuit board mapped--who knows you might get lucky and find one.

Be careful with this approach as even the same model keyboard could have a different model encoder chip and thus a different matrix.

A jukebox should never have more than 1 button pushed at a time, so is all that necessary?

The whole point of doing the matrix is to figure out which wires make which keys.  So which keys do you want to use?

Unless you find a really old keyboard with individual switches, you will need to do at least part of a matrix until you find all the keys you want to use.

The individual switch ones are so much friendlier and easier to deal with though, and when you are done you can mount the whole thing inside the cabinet and still have access to the unhacked keys.

I have done normal modern keyboards, big PCB individual switch ones, and OLD STYLE ones that are almost prehacked, and the big PCB indivdual switch ones are the easiest ones to deal with by far.
