Schematics of Atanasoff-Berry Computer logic circuits?

Indeed it does. Back when I was at Purdue, I knew Saul Rosen who went WAY back. He referred to the push to prioritize Atanasoff as the cult of Atanasoff. But it's so clear that this weird saga really is about the legal/social and not the technical. Both groups innovated in different ways and both are important to study to get a good picture of history and of the evolution in design. Everyone had to address the fundamental question of memory. Eckert and Mauchley knew that it was an eventual issue; Eckert wrote a paper (in 1944 IIRC) where he described a magnetic disk (and even suggested a stored program on it). But in the ENIAC, they largely punted on the question of memory. But Atanasoff's rotating capacitor drum really does stand out as an innovation in memory design. Even if it wouldn't scale well, the rotating, regenerative memory structure is very similar in concept to the recirculating, regenerative delay line memories, like that used in the UNIVAC I. This is the sort of thing that led Eckert to remark that the processing part of the ABC would never have been particularly reliable. His design for the ENIAC was radically different. It bore much similarity to his earlier experience in tube-based counters. And his design techniques were the only reason a machine with 18,000 tubes could be expected to operate for any time at all. Ultimately, we can see seeds of future technology in both machines, but neither machine bore much resemblance to what came after either in terms of architecture or the design of basic functional elements.
