Customer Engineer (CE)/Operator panel for a computer system containing two circuit boards is tested in three ways. The light/switch circuit board and the driver board are each tested separately. Then both boards assembled in the CE/Operator panel are tested. In order to reduce the number of digital input/output connecting points, three different fixtures, which are plug compatible, are used for the two different circuit boards and the panel assembly. Jumper wires (not shown) are connected from microprocessor 50 to whichever test fixture 10 is plugged so as to identify the test mode to be used. Microprocessor 50 uses a program stored in EPROM 40 to test a particular fixture. The fixtures 10 interface to the microprocessor 50 via digital input/output circuits 30 and analog input attachment 20.
