The G. Edward Bryan collection on the CP-6 system contains material on the Honeywell CP-6 operating system and the team that built it at the Los Angeles Development Center (LADC). In an effort to attract Xerox CP-V users to Honeywell machines, the LADC was established in 1976 to develop CP-V’s backward-compatible successor, CP-6. The LADC team was a hybrid of Xerox programmers and Honeywell management, with Bryan as its director. The collection holds LADC’s administrative records, publications, presentation materials, and records relating to the development and releases of CP-6. The collection spans 1955 to 2002. The LADC and CP-6 parts of the collection span 1973 through 2002, but are primarily from 1976 when the project began until 1992 when support for CP-6 was transferred to ACTC Technologies.

G. Edward Bryan received his BS in electrical engineering from Caltech in 1954 and an MS-level certificate in communications from Bell Telephone Laboratories in 1957. He worked in system design and engineering at Bell from 1954 to 1960, then worked at the RAND Corporation’s Computer Sciences Department (also known as the RAND Computation Center) until 1967, where he was on the design team that developed the JOSS-II time-sharing programming language.
