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.
