Diagram entirled "Regeneration and circulation of pulses in delay line". Diagram shows the operation of the mercury delay lines in the CSIRAC computer, Australia's first stored-program computer.

CSIRAC, originally known as CSIR Mark 1, was built by the Commonwealth Council for Scientific and Industrial Research [CSIR], Sydney, in 1949 and was the fourth computer in the world. It was later transferred to the University of Melbourne. Designed by Trevor Pearcey and engineered by Maston Beard, CSIRAC completed more than 1000 projects by the time it was turned off in 1964. It is currently housed at Museum Victoria.

This is one of a set of 35mm slides 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, Cirrus, Atlas, IBM System/360, CDC 6600 System, and Illiac IV.
