This is a really fascinating document. It was written by the lead designer (Howard Aiken) and Grace Hopper, who is well known in CS circles. What I like most about the machine is that it feels easier to understand how it operates in an intuitive way, particularly because it is all in decimal as opposed to binary. And the machine was accurate to a very high number of decimal places, and could also directly produce high-quality printed tables of mathematical tables (the first big job it worked on was to prepare large tables of Bessel functions).
