Answer 2

Imaging the Antikythera Computer

Antikythera_main_fragmentThe oldest known computer, a scientific conundrum for more than a century, did not yield its secrets easily. Only after the most recent innovations were employed, including a $500,000 imaging system constructed in situ, was the mystery of its 81 corroded and mineralized components solved.

Its journey began perhaps 2100 years ago, at the height of Roman Republic, and ended on the sea bed near Crete, waiting two millenia to be recovered by a sponge diver in 1902. It originated, perhaps, from the island of Rhodes, renowned in classical times for its automata and mechanical follies. The Antikythera mechanism, however, was more than a toy: the team of scientists behind the expensive new research announced this week that that they'd solved the puzzle of its purpose, confirming that the mechanical computer was designed to track the movements of heavenly bodies, specifically the sun, moon and planets.

Answer 3

The abacus really isn't a computer, merely a mathematical aid.

Here is a link that details the development from the abacus to to digital.

Answer 4

One carved out of rock was found in a pyramid in Egypt. It took 5 years to decipher the error message, and it was found that the COA was not valid for use on earth.

Answer 5

uh the abacus
