The IME 84 is the first electronic calculator introduced by the Italian company IME. The machine is one of the earliest transistorized desktop calculators produced, introduced in the US at the BEMA show in Los Angeles in 1964. Like other early transistorized electronic calculators, the IME 84 uses Germanium-based transistors, as Silicon transistors were still too expensive. The machine uses a magnetic core memory for register storage, nixie tubes for display, and utilizes a three register architecture.
