IME (Industria Macchine Elettroniche)
IME was an Italian company based in Rome. They produced a line of early, yet very capable electronic calculators that were quite competitive in the calculator marketplace, especially in Europe, in the late part of the mid-1960's. Their initial machine, the IME-84, was quite sophisticated as first-generation transistorized calculators go, and the 86, a follow-on design, continued IME's tradition of excellence.
