The Logos 270 is an electronic table calculator made by Olivetti. It was the first calculator of this company to use integrated circuits.
After the poor commercial success of the Olivetti Logos 328, the Logos 270 allowed Olivetti to position itself more effectively in the electronic calculators market, thus abandoning the creation of electromechanical calculators.
The design, which is due to Mario Bellini, provides a clear separation between the calculation section (right) and the printing section (left). This design was awarded in 1970.
Insights - Fun facts
Logos 270 - in addition to the four basic mathematical operations (addition, subtraction, multiplication and division) - was able to solve square powers, square roots, percentages and accumulations of quotients and products.
An important innovation of this machine was the release: a function through which the user, while holding down a key that had just been pressed, could press a few others.
Logos 270 inherits the use of the magnetostrictive delay line memory from the Programma 101 project. This memory required extreme precision in the assembly, to the point of requiring a microscope. From Program 101 the Logos 270 also inherits the printer's mechanics, capable of printing up to 22 digits at a speed of 25 characters per second.
