Friden 130



4 Functions, RPN

"This is a truly wonderful machine. It is one of the earliest all-electronic calculators. It was introduced in 1963, made by a US company known as Friden (San Leandro, California), which became famous for its high quality electromechanical calculators. The 130 is very big and heavy, partly due to the technology used to build it, and partly because the company that built it was used to building big mechanical machines."
