Photograph of a computer programming diagram entitled "CSIRAC INTERPROGRAM COMPILED 13/4/60 SOLUTION OF QUADRATIC EQUATIONS A(1)Y + A(2)X + A(3)XX = A", followed by columns of numbers.

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