Friden introduced the first fully transistorized desktop electronic calculator, the model EC-130 in June 1963, designed by Bob Ragen. This machine had a 13-digit capacity and a 5-inch CRT display. It used a magnetostrictive delay line for memory (delay line memory) IEEE First-Hand, to save money on expensive transistors. The EC-130 sold for $2200, about three times the price of comparable electromechanical calculators of the time. It was the first calculator to use reverse Polish notation (RPN), which eliminated the need for parentheses to specify the order of operations in complex calculations. In 1965 the company was purchased by the Singer Corporation, but continued operation under the Friden brand name until 1974. Approx. 18" by 24" by 10"
