Photograph of a computer programming diagram entitled "APPENDIX C - AN ILLUSTRATION OF AUTOCODER PROGRAMMING". Written in 1952, Autocoder translated symbolic statements into machine language for the Manchester Mark I computer. It was possibly the first primitive compiler for computers.

This is one of a set of photographs of computer structure diagrams and computer programmimg instructions, probably used in the 1970s as aids in teaching computing subjects. The diagrams and instructions relate to several early models and systems of stored program computers dating back as far as the 1950s and including the CSIR Mark 1 (later renamed CSIRAC), the Cirrus, the Atlas, the IBM System/360 , the CDC 6600 System, and the Illiac IV.
