Summary

I. J. Macaulay worked for Weapons Research Establishment. 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.
