1. Apparatus for identifying a circuit having a known pin configuration and an unknown transfer characteristic among said pin configuration comprising:

  • a socket comprising a plurality of receptacles for holding said pin configuration;

    bidirectional port means electrically connected to said socket, said bidirectional port means being selectively operable for providing input drive, output loading, and power supply conditions among said plurality of receptacles;

    storage means for storing data corresponding to a plurality of input and output parameters for a plurality of circuits of known identity;

    operating means connected to said storage means and responsive to said data for operating said bidirectional port means to provide said input drive, said output loading, and said power supply conditions corresponding to said input and output parameters sequentially for each of said plurality of circuits of known identity; and

    testing means to control said operating means and to provide an identity signal in response to detection of said data corresponding to said input and said output parameters for one of said plurality of circuits of known identity.
