HENZENTRUM UNIVERSITAT KIEL J INTRODUCTION Electronic Associates, Inc. has long been the leader in the field of analog computation. In the last few years, the range of EAI activities has developped into the digital and hybrid domain, to achieve a very significant reputation in the field of scientific computation in general. Established in 1945 in Long Branch, New Jersey, EAI now employs 3,000 people, with yearly sales of over 40 million dollars. Since 1957, the European Division has provided Sales and Service functions here, with headquarters in Brussels (Belgium), and offices in Aachen (Germany), Paris (France) and Stockholm (Sweden), besides, a subsidiary was organized in the United Kingdom : Electronic Associates, LTD. COMPUTATION CENTERS In order to provide users with computing tools and expert applications assistance, several computation centers offer the latest equipment for general computation and simulation purposes, as well as for demonstrations. In Europe, centers operate in Brussels and in Burgess Hill (Sussex, England). Highly valuable experience, developped over a decade of activity in the field, is available from the engineers and mathematicians assigned to the computation centers. Training courses are organized at regular intervals, providing customers with the necessary know-how to efficiently operate and maintain equipment. The purpose of this brochure is to review in summary form, the complete line of EAI equipment.
