Benjamin C. Pierce has posted a gallery of beautiful closeup photos of ENIAC, built between 1942 and 1946, one of the first computers ever contstructed. As Pierce notes, “the immediately surprising thing about ENIAC is its physicality. It is a machine in the most literal sense, built from huge metal boxes, massive cables, thick copper wires joined by gobs of solder, panels full of dials, bank upon bank of vacuum tubes. Looking again, the second surprise is the beauty and intricacy of its individual parts. A single tube, responsible for just one numeral in a decimal ring counter, contains a thicket of wires, planes, and baffles. If you peer very closely, a microcosm of strange and enigmatic scenes begins to unfold.”
