Summary

Users Manual and supplementary information contained in a ringbinder folder. Produced by Digital Equipment Computer Users Society, Maynard, Massachusetts. Made in U.S.A. Issued to the Division of Tribophysics, CSIRO, Melbourne.

The Digital Equipment Computer Users Society (DECUS) was set up by early users of the PDP-1 computer, which was manufactured by Digital Electronic Corporation (DEC), in Massachsetts, United States of America. The creation of DECUS was driven by the need to share information and computer programs for the PDP-1. One of the key reasons was that early users had to write their own software; DEC initially sold only hardware. Set up in 1961, DECUS grew to be one of the largest international societies of computer users in the world.
