Abstract: An optical-mechanical clock for controlling the spacing of data bits recorded on magnetic tape and for controlling the rate at which the tape moves across the recording head. The clock signal is generated by an optical shutter driven by and physically linked to the tape driving source, and positioned between a light source and an optical pick-off. The electrical output of the pick-off is utilized to control either or both the tape speed and the data insertion rate.

Abstract: A source data entry device having a keyboard for data entry, a cathode ray tube for visual display of key-entered data, and magnetic recorders for storing entered data upon cassette-type magnetic tape cartridges, wherein control logic for the keyboard, visual display, recorders, and other input/output peripheral devices is centralized into a central logic unit, and wherein program-controlled data entry is made possible by a wired readonly memory which, in conjunction with the central logic unit, forms a programmed microprocessor whose functional configuration can be altered by changing the hardwired read-only memory.
