Early machines that solved a particular class of problem rather than running general programs. The MADDIDA was a special-purpose digital computer that solved systems of ordinary differential equations, and the Reeves Electronic Analog Computer, known as REAC, was one of a family of early analog computers produced by the Reeves Instrument Corporation. REAC was produced in the United States, and MADDIDA stood for Magnetic Drum Digital Differential Analyzer.
