The Old Calculators Web Museum
“My pages aren’t fancy, focusing on content rather than frilly Web-tricks. These pages are simply devoted to preserving the technology of calculating machines — from the old mechanical calculators of the ’40’s and ’50’s, through the beginnings of the ‘pocket’ calculator in the mid ’70’s, I’m trying to preserve and document some of the wonderful beginnings of the technology that today we take so much for granted.”
