ENIAC, the world’s first general-purpose digital computer, turns 80 years old today — legendary hulking machine was 1,000x faster than its nearest rival

Composed of 40 panels in a U-shape, some of the original ENIAC is still to be found situated on the ground floor of the Moore Building. Students nowadays sit in the shadow of this beastly relic's Cycling Unit, the Master Programmer Unit, a Function Table, an Accumulator, and Digit Trays. Surely, an inspiring presence.

ENIAC needed a lot of maintenance, with several of its vacuum tubes burning out each day. Wikipedia sources estimate it was “nonfunctional about half the time.” Though things improved over time, as engineers became more used to ENIAC’s characteristics.

The ENIAC was officially retired on October 2, 1955. By that time, its binary stored-program architectural successor, EDVAC, was operational. Also in the early 1950s, the UNIVAC I was introduced, and IBM broke onto the scene with its mass market systems and FORTRAN programming. Computers advanced into the IBM PC age in the early 80s, and this came about “all thanks to the ENIAC,” Penn Engineering cheekily asserts.
