PASCALINE - France - 1642 - (1983 Replica)

Pascal's arithmetic machine was the first to be built and to be used. It is estimated that about a total of twenty of these machines where built of which nine are still a part of the world's heritage.
The great invention of this machine is the automation of carrying over of numbers thanks to a system of counter-weights which can provoke a cascade of carry overs.(collection IBM Europe)
