This object is part of a collection relating to the history and development of calculating devices assembled by Assoc Professor Allan Bromley of Sydney University, comprising mathematical instruments, slide-rules, mechanical and electronic calculators, electronic analogue computers, computer components, kit computers, education computers, and associated ephemera.

Allan Bromley was a lecturer and researcher at the University of Sydney Basser Department of Computer Science from 1978 until his untimely death in August 2002. He specialised in Computer Architecture, Computer Logic and in particular the History of Computing. He was regarded as the world authority on Charles Babbage's Calculating Engines (instigating the building of the Difference Engine No.2 at the Science Museum London) and the Antikythera Mechanism and had extensive knowledge of calculators, analogue computers, logic, stereopsis, totalisators, clocks and time keeping and mechanical engineering.

Apparently Professor Bromley bought this model from a scrap metal merchant. His comment was that it is 'not very solicitous'.

Electronic analogue computer, Heathkit Electronic Educational Analogue Computer EC-1, metal / plastic / glass, made by Heathkit Company Incorporated, Benton Harbor, Michigan, United States of America. 1960s

This electronic analogue computer was widely used in industry to train computer programmers and engineers, and in schools and colleges for teaching engineering, physics and mathematics. It is self-contained with the required power supplies, oscillators and an assortment of electronic components for setting up computer problems.

The EC-1 is an early analogue computer. It was designed for educational purposes in the 1950s, and was introduced in 1960.
