Talk:Keyboard matrix circuit

The SY77 has velocity sensitive keys and aftertouch. Using it as an exmaple without more explanation is probably unwise. There is no ribbon cable coming from the keyboard but two bundled cables. There are more wires in the matrix than the explanation provides for.

PC keyboard matrix

All PC keyboards (either USB or PS/2) internally also have a matrix of keys, similar to the description here. In fact a keyboard matrices are very common "staple building blocks" found in almost any design that uses many switches. I propose to change this article to a more generic article about the "keyboard matrix circuit". Unless there is already an article about this, with maybe a slightly different name?

Indeed. You might find inspiration in multiplexer, since keyboard matrices are effectively just specific implementations of that general concept. In fact, including "circuit" in the page name may be overly specific - keyboards on some electromechanical devices (e.g. teletypes) used mechanical components, not electrical circuits, to encode keypresses. Both "keyboard matrix" and "multiplexer" pages deserve to exist, but they ought to reference each other, and I can't swear some content shouldn't slosh from one page to the other.
