Your comments:

  • I remember attending an office equipment fair in London when these machines were brand new and big news.

    The sales rep of Sumlock was explaining the features of the machine and a young lady was doing the demo, the salesman kept saying that Anita will now perform this function, or Anita will calculate this sum.
    We were so amazed that we all thought the young lady using the machine was called Anita!
