Reconstruction of the
Atanasoff-Berry Computer (ABC)
60 years of digital computing
The Atanasoff-Berry Computer was the first electronic digital computer.
Built in 1937-1942 at Iowa State University by John V. Atanasoff and
Clifford Berry, it introduced the ideas of binary arithmetic, regenerative
memory, and logic circuits. These ideas were communicated from Atanasoff
to Mauchly, who used them in the design of the better-known ENIAC built
several years later.
The original ABC was dismantled decades ago. Ames Laboratory, using
private funding, is building a working replica of this historically
important invention. These Web pages tell about our progress, and give
background about this remarkable machine and its inventors.
