A wireless training device is disclosed which uses a digital computer to simulate or imitate electronic circuits, especially logic or computer circuits. Basically, a control program is selected by insertion of an edge encoded card. This card has on it a drawing of the circuit being taught as well as addressing information for use by the digital computer. Test points on the training card are holes, through which the test probe can contact the metal fingers of a test plane. The information derived from the test plane, as well as inputs from the various test switches, are operated on by the computer and control program to give output indications, usually in the form of lights. By putting the control programs in permanent memory (i.e. ROM or PROM) the student will be required to perform few preparatory steps. The unit is expandable by simply adding more programing to the memory chips and by drawing suitable training cards.
