KA10: Update DKB for multiple keyboards.

Browse Source 
The keyboard scanner supports 64 keyboards lines which correspond to
the video switch channels.  Lines 0 to 5 are for the six III displays,
but the emulator only supports one of those for now; it's hardcoded to
keyboard 0.  Data Disc keyboards are 6 to 63.
