City & Guilds Mnemonic Code
1964 British computer specification / From Wikipedia, the free encyclopedia
The City & Guilds Mnemonic Code and its associated City & Guilds Computer was a specification for an assembler language and a virtual computer system that ran it. It was introduced in 1964 by the City and Guilds of London Institute and used as the basis for a number of computer programming and administration courses. The computer model was deliberately very simple, and operational systems were implemented as interpreters on a number of mainframe computers like the ICL 1900 series and Elliot 900 family. An updated version was released in 1968.
