1. An apparatus for making available to a calculator remote programs on at least one memory chip and transferring data stored in said chip into said calculator using power only from a power supply of said calculator, comprising:

  • connector means for connecting said calculator with said apparatus, and supplying a chain of clock pulses from said calculator therethrough to said apparatus;

    temporary storage means for receiving data from said chip and subsequently outputting the same;

    a capacitor connected by said connector means to said power supply for being charged thereby;

    means for operating said chip with power generated by discharging said charged capacitor for a predetermined interval of time between adjacent of said clock pulses to transfer said data stored in said chip to said temporary storage means;

    means for transferring said data from said temporary storage means to said calculator at a slower rate than that which said data was transferred into said temporary storage means from said chip; and

    means for cutting off power being generated by the discharging capacitor to said chip immediately after said data is transferred from said chip to said temporary storage means, thereby minimizing the power requirement for transferring data from said chip to said calculator.
