The purpose of the present invention is to provide an interface board that can easily test the computer by disconnecting the computer and subsystems when an abnormality occurs in a system consisting of a computer and many subsystems.

[Means for solving problems]

Therefore, in the present invention, a test and inspection device is built into the computer, and a power plug for connecting the computer and a plurality of subsystems is used as a monitor means for monitoring the output signal of the computer and as a monitor means for monitoring the output signal of the computer. Attach an interface board to the computer, which is equipped with input means for inputting test signals from the test equipment.

[For production]

If an abnormality occurs in a system consisting of a computer to which an interface board with the above configuration is installed and multiple subsystems, disconnect the subsystem connected to the computer input/output connector, and use a monitor to monitor the computer's output. While monitoring the signal, a test signal from the testing device is input to the computer via the input means to detect an abnormality in the computer.
