The production of a cheep and efficient early era 3(?) transistor microchip for basic electrical functions.
The then standard silicon\germanium etching process.
N/A, but almost certenly a painted poxy/glass filled metal can with 3 metal legs for leads.
|Designed in.||Early 1960s.|
|Made in.||Early 1960s.|
|Transistors per chip.||3?.|
|Power supply.||Low or battery power.|
|Still in use.||Retired in the late 1970s.|
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! It was one of UK's first moves in to the modern electrical business and it was seen as a national icon at the time.
Like all ICs, it is made to a JEDEC standard and ID numbering code after 1953.
