I'm basing my thinking on a publication by Autonetics publication EM-1488 in Jan. 1958. Titled an "Introduction to Digital Airborne Computing Techniques." It's 79 pages self bound book published to bring people up to speed on what is going on. Page 1 is a definition of a digital computer it progresses to number systems, storage devices, boolean algebra, logical design, code design. That is the first half of the book up to page 38. The remaining sections cover General purpose computing, Digital Differential Analyzer operations, Digital Differential Analyzer Programming, D.D.A. decision and servo integration, Incremental and Whole Value Solutions of Control Problems. The book contains a schematic of subsystems and the one complete circuit in the book is of a flip-flop. I think the systems were robust becuase the computing problem was so tightly bound to the hardware.
