The Manchester University Atlas Operating System Part I: Internal Organization
Tom Kilburn · The Computer Journal · 1961
The organization of input and output on the Atlas is described. This is controlled by the supervisor program, and uses varying amounts of core and drum store, supplemented where necessary by magnetic tapes, to obtain, when possible, the maximum overlap between input, computing and output. The system will be used on the Manchester University Atlas, but is suitable for any Ferranti Atlas Installation.
