Inventor: William C. McCall Title: DATA INPUT SYSTEM USING A SPLIT KEYBOARD ABSTRACT OF THE DISCLOSURE An electromechanical interactive terminal system is disclosed, utilizing a split keyboard to accommodate convenient use, even by disabled or infirm persons. The elements of a conventional typewriter (or console) keyboard are provided in two separate and distinct keyboard units, one of which includes the keys normally activated by the right hand while the other has the keys conventionally assigned for use by the left hand. Control and coding keys are similarly assigned. The two separate keyboard units can be used in various positions as by being affixed to a support member so as to be held in spaced-apart relationship, contiguous to the hands of an operator with his arms apart and supported at rest. The keyboard units each incorporate electrical appa- ratus for providing electrical signals representative of data symbols associated with the keys. Additionally, certain keys are coded to provide control signals used in association with display means, a data processor, and a printer. The data processor may include computer memory capabilities as in the form of a floppy disc and is operated to process data as well as driving the display means and the printer. -1-
