They went to great detail in explaining the architecture and operation of these machines. It was also quite interesting how some competitive machines were addressed in great detail, while others were simply glossed over with very basic comparisons.Īn example of a competitive machine that Friden spent a lot of effort to review was the comparison between the SCM Cogito 240 (Yes - there was a Cogito 240.a machine without the Square Root function, though who knows if any survive today) and Cogito 240SR. While generally the comments were resonable, I sometimes found myself shaking my head at some of the “stretches” that were made in terms of how Friden compared their machines to their competitors. In reading through this document, there was a lot of great information contained within, and, for the most part, the comparisons were reasonably fair. The document is quite comprehensive in its coverage, addressing competitive machines from IME, SCM, Olympia, Casio, Dero Research, Sumlock/Anita, Victor, Sharp, Canon, Tohiba, Oi Electric, Nippon Calculating Machine Co., Monroe, Olivetti, Philips, Wanderer/Nixdorf, Mathatronics, Wang, and Wyle Laboratories. It was written as a competitive comparison between the Friden EC-130 and EC-132 calculators versus other electronic calculators on the market in the mid-1965 timeframe. The document that Frank found was clearly intended for internal use by sales and marketing people at Friden. All of the programming work was done in Holland, and while the programming was being debugged, the Friden reps would spend a lot of time on the phone to the engineers in Holland who developed the programming. I do know that a lot of development work on the Friden 5005 Computyper was done in Holland, as my Godparents’ business bought a 5005 Computyper from Singer/Friden, and a bunch of custom programming was done for the particular application they had. was involved in a lot of research and development work. It appears that Friden International S.A. I have not been able to find out much about Friden International, but do know that it was a wholly-owned business unit of Friden Calculating Machine Co., and remained a relatively independent arm of Friden even after Singer bought out Friden in 1963. It was produced by Friden International S.A., in Berg en Dal, Holland.
The document is entitled Electronic Calculators Report 1965. Recently I received an EMail from a fellow old technology afficionado in The Netherlands, Frank Philipse, who had found an interesting document in a used bookstore where he lives.
