Abstract: Apparatus for verifying the operation of mechanisms electrically controlled by operator keyboards which includes delayed electrical sensing of the activation of the mechanisms and alternate printing of data corresponding to the keyboard output signals and to the signals transduced from the operation of the mechanisms. In one version of the verifier the actuation sensing is performed by switches to set a storage means which is then read out after a predetermined delay from the time that data signals are received from the keyboard for storage or printing.
