Scope and Content

(Includes the Speech Converter). This comprises about 150 foolscap pages of ABL code, split for convenience into three green folders. This is the complete set of engineers’ tests for the entire Manchester Atlas system (including peripherals), as at autumn 1964. Contains some hand annotations. Brown paper separators (marked A, B, C, …) were used to distinguish various sections of the program listing, such as central routines, drum tests, magnetic tape tests, etc. it is believed that the initial version of PAT tests was written by Peter Duncanson of Ferranti West Gorton. Eric Sunderland has said that the PAT Test “was the quickest way of making sure the machine was in reasonable order".
