Electronic Associates, Inc. (EAI)
EAI was a major supplier of electrical analog computing equipment in the 1950s and 60s. They played a major role in such high profile scientific projects as NASA’s development of space probes and satellites. They began by constructing analog computers (very useful for simulations of physical systems) but as digital technology became more prominent they created hybrid systems with both digital and analog capabilities.
They remained a supplier of engineering laboratory hybrid computing equipment until the 1970s and even created a subsidiary to enter the purely digital field. As the market changed, they attempted to keep up by changing their name to EA Industries but were later absorbed into other firms.
