Pier Giorgio Perotto's Programma 101

Origin
Pier Giorgio Perotto (1930 – 2002) was an Italian electrical engineer and inventor. Working for Olivetti, he led a design team that built the Programma 101, the world's first personal computer. The innovative computer, also known as Perottina, named after its inventor, was the first computer in history purposely designed to be on a desktop. It was so innovative as it made it possible for computers to be used at home, offices and places previously not reached by huge mainframes of the time. It was officially launched at the 1964 New York World's Fair, attracting major interest from public and press. They sold about 44,000 units, primarily in the US market, starting the next year in 1965. NASA bought ten models and used them to plan the Apollo 11 landing on the moon.
