May 17, 1902: The Antikythera mechanism

1902 – The Antikythera mechanism was found off the coast of Greece. They only found a part of it, and wasn’t really sure what it did. Eventually, this device was declared to be the oldest known analog computer. The device was used to predict eclipses and astronomical events so ships could plan accordingly. The device was found by archaeologist Valerios Stais. British science historian Derek de Solla Price dated the device to 87 BCE. He concluded the device was lost only a few years after it’s production. The low-tin bronze device (5% tin, 95% Copper) made the corrosion impossible to try and start...

the Poppa - SSEC 0

January 24, 1948: IBM Dedicated Poppa in New York City

1948 – At IBM world headquarters, IBM dedicated the Selective Sequence Electronic Calculator (SSEC). The machine – otherwise known as Poppa – was the first computer to combine electronic computation with stored instruction. The 13,500 vacuum tube computer contained 21,000 relays. The 1,800 square foot computer room had a large glass window so the public could see the building of Poppa. IBM created a raised floor for this computer so cables could run underneath and would not be tripped on. This was all in promotion to compete with the ENIAC computer. The first calculations were of the positions of the Moon...
