Abstract
Abstract Three different classes of interface means are connectable to a dual-input matrix or converter, which in turn will operate a device for purposes of communication and/or indicate student capabilities. A unique combination of designators is established for every function in a multiplicity of functions. A device is provided to print, display or perform the function. A matrix or other means transmits signals to the printing or displaying device commensurate with the unique combination of designators selected. Three classes of interfaces are selectively connected to the matrix, one having two sets of input switching means of seven keys each, another having one set of seven keys, and a third having a single input transducer. By use of the same unique designators with each class of interface, an individual will be able to print or display the very same function, regardless of the class of interface used.
