I'm a fan of CHM. That said there collections have (understandably) a rather Silicon-Valley-legacy-centric view of, erm, computer history. You'll find little mention, for example, of these tantalizing early mentions of alternative computer architectures (with pictures!) in NSA's predecessor OP-20-G, as posed alongside the then-nascent von Neumann architecture (also covered).
