Archaeology of Programming: the Hollerith

Archaeologies of programming -- a picture from the Science Museum (London) collections of the Hollerith machine punch card punching machine. Through this you were able to make the punch cards with the statistical information for the late 19th century statistical purposes of US census. To be honest, I think this is a slightly later punching machine than from the 1890 census, but still, principle is the same and illustrates the mechanical nature of coding information on the cards.
