The name originates in a word-play by Zemanek: Even if it cannot match the rapid calculation speed of American models called "Whirlwind" or "Typhoon", it will be enough for a "Wiener Mailüfterl" (which means something like Viennese May breeze).The official name of the machine is Binär dezimaler Volltransistor-Rechenautomat (binary-decimal fully transistorized computing automaton).
