When these beads are moved along the wire according to \"programming\" rules that the user must memorize, all ordinary arithmetic operations can be performed. The next innovation in computers took place in 1694 when Blaise Pascal invented the first \"digital calculating machine\". It could only add numbers and they had to be entered by turning dials. It was designed to help Pascal\'s father who was a tax collector. In the early 1800\'s, a mathematics professor named Charles Babbage designed an automatic calculation machine. It was steam powered and could store up to 1,000 50-digit numbers. Built into his machine were operations that included everything a modern computer would need. It was programmed by, and stored data on, cards with holes punched in them, appropriately called “punch cards”. But his inventions became failures because of the lack of precision machining techniques used at the time and the lack of demand for such a device. By the late 1930s punched-card machine techniques had become so well established and reliable that Howard Hathaway Aiken, in collaboration with engineers at IBM, undertook construction of a large automatic digital computer based on standard IBM electromechanical parts. Aiken\'s machine, called the Harvard Mark I
