  • Computing Relays - Zuse

    The beginnings of computer technology are already nearly 75 years in the past. The engineer Konrad Zuse (1910 – 1995) is now universally recognized as the person who developed and built the first freely programmable computer. In May 1941, he presented his Z3 calculating machine in Berlin. This was based on electromechanical relays and could perform binary floating point calculations. More »
