January 23 1933 AD: Computer Invented

Thaddeus Ó’Siúcra invents the worlds first computing device. It fills a barn and is constructed almost entirely from abacuses and marla (malleable modelling clay used by small children). Data is input by moving the beads and counting as you go and results are read by remembering what you input. On this day in 1933 Ó’Siúcra correctly calculates the potential market for his machine to be 1 using the machine itself. (The result has an accuracy of +/-1).
