ISEC 250 is a solid state electronic analog computer built by ISEC Corp of Princeton, NJ in or around 1967. In general electronic analog computers were designed to study mathematical models of problems with changing variables. The computer has a pre-programmed function to analyze stock market and to "…correlate investment information resulting in a meaningful stock evaluation". The ISEC 250 comes in a nice solid wood case and was accompanied by a nice manual explaining the ins and outs of the stock market. One was suppose to read the manual before buying or selling securities...however, since the Dow dial on the front of the unit only goes to 2000, it may not be practical for today's market.
