Abstract: A master-slave processor human interface system. An electronic device, a slave processor for controlling the electronic device and performing certain computational functions, a master processor for controlling the slave processor, an input device and an output device associated with the master processor, and an information storage device are provided. Individual slave processor programs are selected, retrieved from the information storage device, and loaded into the slave processor for implementing corresponding functions of the slave processor and electronic device, while a single master processor program which adapts itself to the selected slave processor program accepts input data and operational selections and displays output information according to a predetermined spatial arrangement for each such function, thereby providing the human interface.
