The journal Electronics Design announced this "Inexpensive calculator" in August 1971, at a cost of US$545, and a British list of November 1971 gives a price of £288 GBP. Made in the Japan (by Hitachi) for Singer-Friden of the USA about 1971-73. This would progress much further (for instance with the hand-held Friden 1234), but Singer-Friden would soon leave the calculator market. Bien que n’ayant pas été utilisée à Grenoble, cette machine, datant de 1964, présente un intérêt majeur pour la collection, puisqu’elle signe l’acte de naissance des calculatrices électroniques modernes.
#Friden calculator ec1113 movie
Let's try it out, it's way more impressive than in the movie (I suspect theirs didn't work fully). L’ACONIT vient de recevoir en don une calculatrice électronique Friden EC 132 (EC pour electronic calculator). Significance: By this time in the evolution of Friden electronic calculators (see the earlier Friden EC-132 and EC-1114 models) the use of a few LSI ICs had drastically reduced the number of electronic components. Yes, this 1956 Friden STW10 is the calculator machine on the desk of Katherine Johnson in the movie Hidden Figures. Alright, so I was initially pretty sure this Friden was going to take hours and hours to get even to a functional state with how badly it looked both externa. By the 1960s they had abandoned the mechanical. Headquartered in Oakland, California, by the mid-1950s the company had sales and service offices in several hundred places in North America and Europe.
Technology: 9 Large Scale Integrated ICs (LSI) and 3 Small Scale Integration (SSI) ICs by Hitachi, and 13 discrete transistors. Founded by Carl Friden (1891-1945) in 1934, Friden was one of the leading providers of high quality mechanical calculating machines. A description of the primary functions of the Friden electro-mechanical calculator.
Distinctive features: Has a single circuit board with 9 Large Scale Integrated Circuits (LSI) by Hitachi.ĭisplay: Display is 12 digits, using 'Nixie'-type tubes.
