In 1965 the company was purchased by the Singer Corporation, but continued operation under the Friden brand name until 1974. The successor model EC-132, introduced in April 1965, added a square root function. 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. The EC-130 sold for $2,200 (equivalent to $18,600 in 2020), or about three times the price of comparable electromechanical calculators of the time. It used a magnetostrictive delay-line memory, to save money on expensive transistors. This machine had a 13-digit capacity and a 5-inch CRT display. Friden eventually expanded into production of a few models of early transistorized computers.įriden introduced the first fully transistorized desktop electronic calculator, the model EC-130 in June 1963, designed by Robert "Bob" Appleby Ragen. The Flexowriter could be attached to Friden calculators and driven by paper tape to produce bills and other form letters which had names of customers and amounts of bills filled in automatically. This gave them the Flexowriter teleprinter, an electric typewriter capable of being used as part of unit record equipment developed in World War II for the Department of the Navy to automatically type "regret to inform you" letters to the survivors of fallen servicemen, the predecessor to modern computers. In 1957, Friden purchased the Commercial Controls Corporation of Rochester, New York. ![]()
