The Laptop Engineering Technology program prepares graduates for careers in sustaining, manufacturing integration and help of computer techniques. Whereas many early digital computer systems had been based on similar designs, such as the IAS and its copies, others are distinctive designs, like the CSIRAC. In-built Sydney, Australia by the Council of Scientific and Industrial Research to be used in its Radio physics Laboratory in Sydney, CSIRAC was designed by British-born Trevor Pearcey, and used unusual 12-hole paper tape. It was transferred to the Division of Physics on the College of Melbourne in 1955 and remained in service till 1964.
