  <!-- 
  Based on Werner Kai's machine with serial 136396.

  The machine has a built in touch pad. It can be disabled with a switch on the
  left side of the machine.
  The touch pad is internally connected to joystick port A. Touching the pad
  triggers 'trigger A' and the blue button left of the touch area triggers
  'trigger B'.
  It behaves like a standard MSX touch pad.
