A 12-page product brochure (Bulletin No. AC65064, September 1965) from Electronic Associates, Inc. describing the EAI 680 Scientific Computing System, a hybrid analog-digital computer. The brochure covers applications across process industries, universities, life sciences, and aerospace, and highlights hybrid capabilities including electronically addressed servo-set potentiometers, parallel digital logic, 500 kc bandwidth operational amplifiers, and track/store units with sub-microsecond reset. The console houses up to 156 amplifiers, 120 potentiometers, quarter-square multipliers, and variable diode function generators in a compact 5 x 5 x 2.5 foot welded steel frame operating on 10-volt solid-state circuitry.
