Friden 130 Friden USA 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." Rick Bensene Source: Rick Bensene's Old Calculators |
