Since Thorsten released a 8*8 scan matrix driver,

it's easily possible to use a C64 Keyboard with MIOS.

The C example can be downloaded here :

First, i did this pcb (on a breadboard) :

Use that sample program to test your keyboard connection :

• http://jambonbill.free.fr/midibox-kb/c/c64-keyboard-test-v2.zip (sources are included)

This small app display the key number, the corresponding Character, the midi note number associated to that key, and play a note on channel 1. The keyboard mapping can be found in the “variables.h” file. More than a test, it's a good base for your own programs.

A bigger and more interesting program (a funky sequencer) is still on developpement… stay tuned !
