Schematics of Atanasoff-Berry Computer logic circuits?

I can't help but see Eckert as one of the truly brilliant engineers of the 20th century. Thanks, but my wife gets really annoyed at how long it takes me to compose considered responses to her. :-) Indeed, almost everything was quite incremental when you look at what everyone else was doing. Just a sampling with no intended disrespect or suggestion of insignificance for those left out: 1933-1941 - Mauchly's experiments with neon bulbs for digital circuits (I couldn't find an exact date but it was while he was at Ursinus which was between 1933 and 1941.) 1937 - Shannon's MS thesis on binary numbers and Boolean algebra - George Stibitz' Model K binary half adder with relays 1939-1944 - Development of the Harvard Mark I (Aiken) with relays and rotating decimal components patterned in part after Babbage 1940 - The Bell Labs Complex Numerical Calculator extending Stibitz' binary relay system to a full calculator 1941 - The ABC implementing binary with active electronics 1942-1945 - Development of the ENIAC using active electronics in a "rotating" decimal way and even more general than the Harvard Mark I 1944 - Beginning of EDVAC design and introduction of the stored program idea using active electronics in binary 1945 - von Neumann's "First Draft" paper making the design ideas for the EDVAC widely known 1946 - The summer school on computers at U Penn attended by those who went back and developed the Manchester Mark I and the EDSAC 1948 - The ENIAC reconfigured to operate as a type of stored program machine 1948,9 - Manchester Mark I operational 1949 - EDSAC and EDVAC operational So given all these events over a period of 15 years or less, who invented the computer? That was rhetorical, in case it wasn't obvious. Unless we say it was Babbage for the idea and partial implementation of the automatic sequencing of mathematical operations in a mechanical system or was Eckert, and independently Zuse, for the stored program, I don't think there's really anyone who can be said to have invented the computer. But rather the best approach to "compute these numbers by steam"* grew organically through the work of numerous very bright people. I agree. There are many people who are pretty much unknown but who were the intellectual foundations of everyday life. It seems that it's easier to popularize someone when they build something that can be shown on TV than when their contribution is strictly intellectual. Einstein and Hawking were interesting people which drew peoples' attention to their work. It's like with Church and Turing. Both developed universal models of computation at about the same time, but Turing is by far the better known. A lot of it comes from his work at Blechley Park, his work on the pilot ACE, his excentricities (like chaining his coffee cup to the radiator and riding his bike with a gas mask on), and of course the tragic circumstances of his death. Well, intended for the lay person or not, I'd like to see something like that. BLS * The computing numbers by steam is a paraphrase of a statement Babbage made as a student that led to his work on the differential engine and later the analytical engine. He was staring at a book containing mathematical tables and a friend asked him what he was thinking and that was his answer. Hmmm come to think of it "Computing Numbers by Steam" would make a good title for a book on computer history...
