1. A data telecommunications terminal for use with a telephone system comprising:

  • (i) memory means for semi-permanently storing data;

    (ii) signal generator means for generating signals corresponding to said data;

    (iii) signal coupling means coupled to said signal generator for coupling said signals to said telephone system;

    (iv) a keyboard having a first group of switches for inputting data, a second group of switches for directing the storage of said data, and at least one switch for directing the generation of signals corresponding to said data;

    (v) a microprocessor coupled to said memory means, said signal generator means and said keyboard for controlling, under the direction of said keyboard, the receipt of said data from said keyboard, the storage of said data by said memory means, the generation of said signals by said generator means, and the supply of voltage within said terminal, whereby said data is entered into said memory means from said keyboard and said data is coupled to said telephone system from said memory means, and;

    (vi) self-contained power control means coupled to said memory means, said keyboard and said microprocessor for providing voltage substantially only during actuation of said switches, said power control means activated upon actuation of any one of said switches and automatically deactivated by a command from said microprocessor upon completion of processing by said terminal.
