The single view shown is a top perspective view of a compact disc player showing our new design. The main body includes a breech and a feed port connected and a feed tube connected thereto. Authorization to change presence data is given to another selected user upon user release. Programming circuitry is coupled to the gate of the first transistor and the gate of the second transistor and configured to in a programming mode apply a potential of either zero volts or VPP2 to the gate of the first transistor and to apply a potential of VPP2 to the gate of the second transistor.
