Punched cards for programming the Analytical Engine, 1834-71 "Babbage intended to use punched cards to feed instructions and data into the Analytical Engine. The smaller cards are 'Operational Cards' which specify the mathematical operations to be performed - multiplication, division, addition or substraction. The larger cards are 'Variable Cards' which dictate where the numbers to be operated on are found in the machine and where the results should be placed." Science Museum, London |
