A: Brookline, Massachusetts, United States
In 1961 engineers at Compugraphic in Brookline, Massachusetts recognized that a computer could be programmed to handle repetitious typesetter coding automatically. The firm developed a prototype model of the Directory Tape Processor (DTP) which eliminated all operator decisions, and produced a fully coded tape used for typesetting.
When I searched in September 2020 I was unable to find any images of this system on line. Brief references to it appeared in Stevens & Little, Automatic Typographic-Quality Typesetting Techniques (1967).
