During the 1950s he was involved in designing a special machine to predict impact positions of missiles while in flight. The design of this machine, the ATROPOS (or DIP), was a transistorised version of the TREAC, provided with a special built-in square root operation which was needed to achieve the very high execution speed to predict at a rate of 5 times per second. 1947 1947 Career event - Student Member (StudIEAust), Institution of Engineers Australia c. 1950 Career position - CSIRO Mathematical Instruments Section c. 1953 c. 1953 Education - Bachelor of Engineering (BE), University of Sydney? c. 1955 Career event - Engineer, Weapons Research Establishment, South Australia 1957 1957 Career event - Visited the United Kingdom, when Trevor Pearcey was at the Radar Research Establishment on TREAC 1975 1975 Buried - Northern Suburbs Memorial Gardens and Crematorium Keith, Ron J.
