1. A microcomputer comprising:

  • electrically powered data processing and storage components for processing and storing digital data, anda pulse width modulation switching power supply for connection with an alternating current electrical main supply and for supplying direct current electrical power to said data processing and storage components for enabling operation thereof, said power supply comprising;

    a controllable component for responding to the presence and absence of a low voltage direct current electrical signal by enabling and disabling the supply of electrical power to said data processing and storage components, anda signal generator circuit operatively connected with said controllable component and with an alternating current electrical main supply for controllably deriving from the main supply a low voltage direct current signal for delivery to said controllable component, whereby a user of the microcomputer may control energization of the electrically powered data processing and storage components by controlling the application of said low voltage direct current signal from said signal generator circuit to said controllable component.
