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
