An enormous advance was made by the mid-1960s with the development of equipment that projects the characters from CRT screens. Alphanumeric Corporation (later Autologic) produced the APS series. Rudolf Hell developed the Digiset machine in Germany. The RCA Graphic Systems Division manufactured this in the U.S. as the Videocomp, later marketed by Information International Inc.. Software for operator-controlled hyphenation was a major component of electronic typesetting. Early work on this topic produced paper tape to control hot-metal machines. C. J. Duncan, at the University of Durham in England, was a pioneer. The earliest applications of computer-controlled phototypesetting machines produced the output of the Russian translation programs of Gilbert King at the IBM Research Laboratories, and built-up mathematical formulas and other material in the Cooperative Computing Laboratory of Michael Barnett at MIT.
