scanning keyboards

I'm currently working on a tb-303 clone and I'm trying to replace the
microcontroller with a z80 based system, but I have a problem: how do
you scan the keyboardmatrix and the ledmatrix? I have read several books
on z80 programming but none of the books I've read give any clues about
scanning keyboards with a z80. Does anyone know if there are books on
this or a net resource.
Thanks Heiko
