  1. I am looking for the history of a Contex Weight Calculator made in Denmark. I cannot find the history on it.
    Thank you

  2. Phillip,
    I have 4 Pac’s of HP-65 magnetic cards. One Standard Pac 1, one Stat Pac 1, one E.E. Pac 1 General, and one case that has 40 magnetic cards; I assume they are blank. I would like to find them a good home. Any help would be appreciated.
    Thank you,
    Pamela Farver
