PORTABLE COMPUTER WITH LARGE SCREEN DISPLAY ABSTRACT OF THE DISCLOSURE: A portable programmable electronic computer, typically pocket sized, has very few keys to accomodate a large display screen, and thus produces alphanumeric and graphical display capabilities compatible with comprehensive alphanumeric computer operations in data processing and data communications. To achieve this the keyboard is typically as few as twelve or sixteen keys laid out with ample spacing for manual fingertip actuation without interference. Correspondingly 144 or 256 entries for alphanumeric data and computer command signals are available in a two-stroke per entry keyboard operation mode. A chart of input keystroke sequences provides on the keyboard itself the necessary dictionary of available operations without reference to outside manuals. By means of a tape recorder with computer interfacing, audio processing such as dictation and large scale digital storage of software programs, etc. is under control of the keyboard for selection of different modes of operation, including comprehensive word processing with the on-line large area multiple line alphanumeric display available.
