ABSTRACT:
Utility of keyboard controlled multipurpose calculating computers with large numbers of modes of operation on data is substantially increased by making available these modes of operation with fewer keys on the keyboard and relating-the keyboard keys to integral keyboard panel carried operating instructions identifying hundreds of accessible operating steps and functions. Typically 12 or 16 key keyboards will initiate considerably more than a hundred different input characters and instructions each clearly identified so that the computer can be used for most of its intended purposes at all times by relatively unskilled operators without reference to instruction manuals. The operating mode requires two successive instantaneous keystrokes for one entry, and the two keystrokes necessary for each of the accessible operating modes and input characters are displayed adjacent the keys for indicating the keys to stroke for each desired entry.
