From Wired:
Emil Dudek, a technology enthusiast who lives in South Wales, U.K., has spent the last eight years acquiring calculators made in the 1970s, taking them apart, photographing them, analyzing the technology and posting it all to his website along with specs and comments on each machine.
It’s one man’s digital ode to electronic calculators. For Dudek, who got his first electronic calculator at the age of 15, in 1976, the devices represent a snapshot in time — a moment at the cusp of a digital computing revolution.
