ABSTRACT:
A computer keyboard matrix overlay panel carries indicia indicating the functions of keys and other operating instructions, to replace a significant part of the information formerly set forth in an external instruction manual. Individual panels are coded by incorporated switch parts acting with cooperating computer switch parts to set up a particular operating mode for which the respective key functions are identified when the panel is in place over the computer keyboard keys, the functions being selected by the use of two sequential, non-simultaneous keystrokes involving any of the keys on the keyboard. The panels also serve as software media by incorporation of data strips along panel edges to permit carrying program and data information external to the computer memory which is readable into the computer by corresponding transducers. The panel codes can change the comptuer mode and enter corresponding programs, subroutines, constants, and variable data. With three separate code strips: data, program steps and subroutines are isolated advantageously for entry at different times. Optically coded data strips are used for read only memory for program steps. Magnetically coded strips are used for read-write memory into corresponding reading apparatus coupled to the computer for data which is updated after processing in the computer.
