The work in the late 40s was interesting, too. First, you had specialized systems, then Eckert, Mauchly, and von Neumann started working on stored program computers. They had to figure out what opcodes were needed and how they were going to be implemented. Jean Jennings Bartik's book (http://www.amazon.com/Pioneer-Programmer-Jennings-Computer-C...) is a great first-hand account of all the work (and drama) from back then.

(Not trying to short-change Bartik here either -- she did a lot of the work on the ENIAC instruction set when they converted it to a stored-program computer)
