Z80-KEYBOARD(5)                Keyboard mapping                Z80-KEYBOARD(5)

NAME
       description of keyboard mapping used by IN on port 0.

DESCRIPTION
       If there is no readable file keyboard_map then there is a one-to-one
       mapping of characters to key codes. The key code 0 means no character
       input.

       If there is a readable the file keyboard_map , it must contain a
       mapping of key codes to characters.  Each line of this file is either a
       comment line or a mapping line.  A line starting with two hexadecimal
       digits followed by a Space is a mapping line else it is considered as a
       comment line and ignored.

       The first two hexadecimal digits of a mapping line indicate the
       keycode.  This must be unique in the file. Next in column 5 follows a
       printable character (Ascii code > 32) and a Space or in column 5 and 6
       are two hexadecimal digits or columns 5 and 6 contain both a Space. The
       last case indicates that this key code is unused by the keyboard. In
       the first two cases the character in column 5 respectively the
       character identified by the hexadecimal number in column 5 and 6 is
       mapped to the key code.  If colum 7 exists it must be a Space and
       further columns in the line are ignored.

       The first two mapping lines must describe unused key codes. The first
       key code is used to denote the case no key was pressed on the key board
       and the second mapping line denote the case an unknown character is to
       map to a key code.
