D-22698 ABSTRACT OF THE DISCLOSURE Apparatus for monitoring and controlling the operation of a program-controlled computer. The program causes the computer to produce a signature waveform characteristic of proper computer operation at a dedicated output. The presence or absence of this waveform indicates whether or not the computer is operating properly. The apparatus monitors this output and the power supply conditions applied to the computer. Whenever the power supply is operating outside of certain limits the apparatus produces a reset signal to the computer and a disable signal to any equipment which is being operated under control of the computer. If a malfunction occurs in the computer operation, the apparatus produces the disable signal and a reset pulse. If the malfunction is cleared during reset, the computer returns to normal operation upon termination of the reset pulse. If the malfunction is not cleared and the normal operation is not resumed upon termination of the reset pulse, the disable signal continues and no further reset pulses are initiated.
