    I'm not 100% sure but I think this company. hardly more than a footnote in >> computer history, was the cause of little-endian processors.

    Guess again

    Try the DEC PDP-11 (1969)

    Yup. The PDP-11 was definitely the first byte addressed machine with little-endian byte order.

    I have looked through every scrap of documentation I can find, and I have never found an explanation of why they did that. They definitely knew it was different
    from all the existing byte addressed machines.

    Please do us all a favor and DO NOT send in your guesses about why they did, unless they include verified quotes from people who were at DEC in the 1960s. --
