One of the first fully electronic calculators. Display on oscilloscope-type screen.
Released in 1964 in the USA, the Friden EC-132 was one of the first fully electronic calculators in the world. It operated like a 4 stack register RPN calculator; cache memory was a nickel wire delay line memory. 8 main logic boards, all transistorized, no IC's. The model on display has been donated by Pierre van Huffle, a former Friden technician.
