Goldstine worked with Eckert and Mauchly on the ENIAC, with them and Von Neumann on the EDVAC, and the joined VN at the IAS, so there’s a clear slant, and a bit of score settling, to that section of the history, but it’s also a plus in its hands on participant point of view. The first third of the book is actually about the Victorian and Belle Époque precursors to modern computers, (Pascal, Babbage, etc) which was surprisingly entertaining. Some sections get bogged down in some pretty heavy math/computational theory, but you can lightly skim those parts without missing any of the history...
