“A microcomputer based system for automated pattern digitization and editing” by Pavliscak, Stowell and Bailey

Since the first microcomputer was produced in 1969 by Intel Corporation to support the functions of an intelligent terminal, the complexion of digital computers has changed radically. Microcomputers have been successfully applied to a wide variety of dedicated tasks requiring relatively slow calculation speeds and limited numeric accuracy.

However, little has been done to bring the LSI microprocessor into stand alone interactive graphics systems. This has been so probably because of the large data files and rapid computation speeds demanded by most interactive graphics applications. This paper outlines a hardware and software configuration for a microcomputer based graphics system developed in response to a need in the sewing industry for a low cost pattern digitizer.
