A coordinatograph is an instrument which mechanically plots X and Y coordinates onto a surface, such as in compiling maps or in plotting control points such as in electronic circuit design. One historic application of a coordinatograph was a machine that precisely placed and cut rubylith to create photomasks for early integrated circuits including some of the earliest generations of the modern PC microprocessor. The coordinatograph produced layout would then be photographically reduced 100:1 to create the production photomask.
