English: Photo of a 'Pascaline', the mechanical calculator invented and manufactured by French scientist Blaise Pascal between 1642 and 1652. The device was made in various versions; this version was made for adding French currency. The wheels are marked with the denominations, from least significant on the right: deniers; sols (= 12 deniers); livres (= 20 sols); and then 10 livres; 100; 1,000; 10,000; to 100,000 livres on left. So the machine could represent up to 999,999 livres. To enter a digit in the device, a stylus was inserted between the appropriate wheel's spokes and the wheel was turned until it reached the stop at the bottom, like dialling a telephone. Each digit was entered in turn, and the sum would appear in the windows at top. The device could only add, and subtraction had to be done with nine's compliment addition. Alterations: deleted figure number, rotated image to justify, and increased brightness. |
