Cambridge Computer History Information from CUCPS

We hope to make available from this site information about computer history (mainly in Cambridge). So far we have copies of some documentation relating to Cambridge systems (more may be added in future, where the appropriate people give permission). We are grateful to David Hartley, Philip Hazel, Charles Jardine, Barry Landy, John Line, Roger Needham and Martin Richards for their assistance in supplying documents, software, information or advice and for giving or obtaining permission to distribute these materials.

• Information about TITAN
• Specification of ZED (SPEC.ZED) (HTML 162k). ZED was a programmable text editor on the IBM mainframe Phoenix, in which people wrote obfuscated programs to do such things as calculate primes. For information on the ZED source distribution (in IBM assembler), including a testsuite, and on Philip Hazel's more recent NE editor, see our 1998 to 1999 talks page.
• A Proposed Definition of the Language BCPL, 1979. This is a draft standard; I am not aware of a final version. Unlike the formal definition given in the book BCPL - the language and its compiler by Martin Richards and Colin Whitby-Strevens (CUP, 1980), this version includes a specification for the standard library.
