  • What a wonderful clunking, whirring, noisy beauty! I used one extensively from 1961 when I was with the insurance group American International in Bermuda. It truly was the latest thing then!

    In the 80s I bought one at auction; it was in good condition, rattling away to perform its magic, but after a decade of only very infrequent use, it jammed and I didn't seek to have it repaired. I regret having thrown it out, but the memories linger.

  • I used one of these machines in the mid to late 1960s to do statistical calculations for experiments conducted on dairy processing equipment. This was at the New Zealand Dairy Research Institute, Palmerston North, New Zealand. It was quite fun to use as it was accurate and it was noisy and would churn away as it processed the numbers.

  • I was a field serviceman from 1967-1979 for the Friden-Singer-TRW Business Machine Company in Manhattan, New York City, NY and this line of calculators was one of the most well built and reliable of any type of machine that I've ever come across.
    Miss repairing them!

  • This is what I used in my college statistics class in 1963! It was a "state of the art" desktop calculator!
