User's Manual for PCBOARD.
Abstract:
PCBOARD is Super Tool-a digital computer program used to design the layouts of printed circuit boards. Not a substitute for printed circuit layout experience, it rather provides the designer with the use of an interactive graphics terminal functioning as an electronic drafting board. Layouts can be generated on the face of the graphics screen thru the optimum placement of components and construction of the conductor paths interconnecting their common leads. A computer driven plotter produces inked drawing copies of the completed screen layout or when equipped with an optical exposure head this same plotter can produce an actual size artwork master of the conductor pattern directly on photographic film for use in the manufacture of the board.
