Abstract
An electronic testing device comprising a housing, test overlays, at least one data entry overlay, operating mode selector means and a microprocessor and associated circuitry. The testing device is arranged for either a testing mode of operation or a data entry mode of operation, with either mode being effected in response to the operating mode selector. The test overlays are each arranged to be releasably secured to said housing and bear indicia forming a plurality of questions and a plurality of possible answers corresponding to the questions. The overlays additionally comprise coding which cooperates with input on the housing to specify a set of correct answers to the questions when the device is in the testing mode. The housing additionally comprises plural electrical contacts arranged when actuated by an electrical probe to select a desired answer for each of the questions and for providing an electrical signal indicative thereof. The microprocessor and associated circuitry are responsive to the signals for determining the degree of correspondence between the answers selected and correct answers to the questions to produce scoring information. The data entry overlay defines a plurality of alphanumeric characters on the housing and associated with respective ones of the plural contacts, whereupon the actuation of each of said contacts provides an electrical signal indicative of a respective one of the plural alphanumeric characters. The signals representing the alphanumeric characters are provided to the microprocessor and associated circuitry so that the device can provide output signals representing selected data which was input during the data entry mode as well as the scoring data produced. These signals are used by an associated printer to print a report based on the test results. An optional computer or some other peripheral device can also be connected to the device's output.
