    Extra SMEC chip ---help needed

    I am working on a MP SMEC and it has an extra chip at the location at Z64 just above the 0 ohm jumper mid board approx. 2" from the right side. Harris semiconductor CDP68HC68S1E
    Anyone know the function of this Serial Multiplexed Bus Interface?? None of my dozen or more SMEC has this.
