ABSTRACT:
More computer commands in multi-purpose programmable electronic computers are made with fewer keys in keyboard assemblies having therewith integrally located instruction indicia showing a key stroke sequence for selection of a large range of instruction commands. In achieving this the computer operates in at least two modes with one mode requiring two key strokes in mutually exclusive time sequence for each command entry. In a preferred embodiment, a single stroke mode is used for numerical entries and a third mode provides for facilitated alphanumeric entries for writing programs in a simplified form. The keys, strokes, and command instructions are cooperatively integrated by means of coded indicia which permits condensed display of a large range of the computer instructions available from a few keys so that reference to manual instructions is not necessary.
