The chips in the two former products apparently were made in the United States, with assembly of the calculators in Taiwan. The tape could then be sent to the typist who copy from the audio tape. The Unisonic Xl-101 and Lloyd's E680-3 are virtually identical to the Radio Shack EC-2001 just mentioned. The dictator also had the ability to erase unwanted sections of the dictation and re-record onto the same tape. Using magnetic belt, this machine could record up to 14 minutes of audio.

Stanley Jevons of the Royal Society wrote of the Arithmometer: The amount of time saved will vary with the character of the operation and the nature of the calculations but about the saving of mental exertion there can be no possible doubt. To operate the Arithmometer, numbers are input by setting dials across the interface and then the crank is turned to produce an answer. 1022, and so was likely produced in the early to mid-1870s. In around 1872 Thomas de Colmar’s became the first to manufacture over 1000 calculating machines.
His mechanical calculator was exhibited Paris Exposition of 1867 and performed simple multiplication and division. This Arithmometer was invented and patented by Charles Xavier Thomas de Colmar (1785-1870).
