Long before anybody dreamed of a shiny iPad or glistening ultrabook , engineers and scientists used to get down to business with mechanical calculators to cipher their solutions . While the construct of a mechanical calculator sounds preposterously bare these days , a peek inside one bring out that they ’re anything but .

In its Clarence Day , it sold for sold for upwards of $ 1,000 — that ’s over $ 7,000 at today ’s rates . OK , so there ’s a special amount you could really get done with such a machine , but the craftsmanship , engine room and sheer complexness of the 505 is staggering . [ Kevin TwoneviaDvice ]
