The idea[]
The production of a cheep and efficient early era 3 transistor microchip for basic electrical functions.
Manufacturing[]
The then standard silicon\germanium etching process.

It was meant to replace transistors like the American 2N34 PNP Germanium Alloy Junction Transistor, so the circuit would have 1, not 3 cans on it!
Like all ICs, it is made to a JEDEC standard and ID numbering code after 1953. It was one of the Netherlands's first moves in to the modern electrical business and it was seen as a national icon at the time.
Casing[]
A 3 legged metallic TO-18 transistor packing unit shell. T-18 stands for Transistor Outline Package, Case Style 18. It was often mistaken for the 2N107 germanium alloy junction PNP transistor (General Electric (GE)) transistor at the time.
