Notes:

1/ The  cursor  keys  are special -- the shifted cursor keys appear as
   separate  keys,  but  in  actuality pressing them generates a SHIFT
   plus  the normal cursor code,  making them totally compatible with,
   and therefore functional in, C64 mode.

2/ There are a total of 77 keys, two of which are locking keys.

3/ The NATIONAL keyboards are similar,  and their layout and operation
   is identical to their C128 implementation.

Keyboard Notes:

1/ The  64 keys under C0 through C7 occupy the same matrix position as
   in the C/64,  as does the RESTORE key.  Including SHIFT-LOCK, there
   are 66 such keys.

2/ The  extended  keyboard consists of the 8 keys under the C8 output.
   Counting the CAPS-LOCK key, there are 9 new keys. The C/64 does not
   scan these keys.

3/ The new CURSOR LEFT and CURSOR UP keys simulate a CURSOR plus RIGHT
   SHIFT key combination.

4/ The  keyboard mechanism will be mechanically similar to that of the
   C128.
