Vintage Calculators

All you young whippersnappers probably have not given much thought to what were used for calculators prior to the wonderful electronic devices that we have today. No, we didn't use marks on clay tablets. There were wonderful mechanical devices that did calculations. Friden and Marchant were the big names. I remember playing on a Marchant in my dad's office very much like this one.

I was involved in sports car rallys in the late 60s and this was the calculator of choice.

Mechanical marvels from an age lost in the mists of time. That would be about 35 years ago.
