i am trying to interface keyboard KM 2601 (AMKETTE) & the
           16 * 2 LCD with microcontroller 89C51 . The interface
             should be such that any  A-Z characters & 0-9 numbers                  pressed on the keyboard should appear on the display.
                the other special function keys of the keyboard are       simply ignored.
      Also the thing is that the keybord has the cord which has 5-pins. how to connect it with MCU ? How to get exact key from these pins ?


          can you help me in the circuit connection and the       programming ? (it is very urgent)

                 Thank you.
