  1. Ancient Computing Devices Created by Zack Johnson Presented by Ryan Bailey

  2. Overview ENIAC Mark 1 Conrad Zues’ Z1 Babbage’s Analytic Engine (1830) Babbage’s Difference Engine (1820) Jacquard Loom (1801) Pascaline (1642) Antikythera Mechanism (100 BC) Abacus

  3. Abacus Calculator in ancient times Used in Ancient Greece, Rome and China

  4. Antikythera Mechanism Considered first actual computer Tracked seasons, eclipses(even partial ones), planetary motion, and festivals

  5. Pascaline Arithmetic machine built ~1643 Only preformed addition and subtraction Made for his father, a tax collector

  6. Jacquard Loom Loom that operated on punch cards Charles Babbage adopted the idea of punch cards

  7. Babbage’s Difference Engine Babbage’s first attempt at a computing device Designed to work with polynomials Would have stood 8’ tall and weighed 4 tons Funding discontinued

  8. Babbage’s Analytic Engine • Four parts • Mill (think CPU) • Store (Memory) • Reader (Input) • Writer (Output) • Held up to 1,000 50 digit numbers • Connected with Ada Lovelace

  9. Z1 22-bit computing machine built in 1936 First programmable computer using Boolean Destroyed in the bombing of Berlin

  10. Mark 1 First computer bug Debugging was literally removing a moth Unsung hero Grace Hopper

  11. ENIAC First modern computer Constructed originally for the United States Army Calculated up to 2400X faster than a human
