...It performed automatic sequential control, and thus contained the basic concept of today's computers. The first purely electronic general-purpose computer, which used vacuum tubes instead of mechanical elements for calculations, was the ENIAC, completed in 1946 by J. Presper Eckert Jr. and John W. Mauchly (recent research suggests that the ABC, prototyped by John V. Atanasoff around 1942, preceded it as a purely electronic computer, although it was less versatile). However, ENIAC was not strictly a stored-program computer, as the program was entered by rewiring the wires using plugs. ... *Some of the terminology that mentions "Eckhart, P." is listed below.
