    Re: Calculator v. Slide Rule for Ex-Meridian Correction
    From: Paul Dolkas
    Date: 2016 Jan 3, 15:58 -0800

    Although I also have a soft spot in my head for slide rules (I carry a circular one around with me on my watch), I feel it’s my duty to point out that by the end of the Apollo project – the 1975 ASTP joint flight with the Russians - NASA was flying an HP 65 programmable calculator as a backup, and they ditched the slide rules.

     

    Sorry - Paul
