    Re: Bob Goethe's Mark 2 Navigators slide rule, test drive comparisons.

    Hello Sean,

    1. I understand the one sided scale.
    2. Oh a kind of agenda organiser, in Europe we have still the well known SUCCES agenda.
        I used from 1991 or so the Psion Series 3 electronic organiser. With a real keyboard.
        I bought my first electronic Celestial program for this organiser, it worked not very nice as I remember.
        When it broke down, it was replaced with a Palm PDA. I still use one old TREO Palm phone
        only for a few (celestial) programs as a back-up. Most is now done with TI-89 Starpilot calculator.
        During my education to Electronic engineer I have used many years slide rules. I still have a few
        but never use them.
    Thanks for your info
