> Those problems would probably have been easy to fix, but there existed another aspect of the first edition that continued to bother me. I wanted to show the workings of an actual CPU—the central processing unit that forms the brain, heart, and soul of a computer—but the first edition didn’t quite make it. I felt that I had gotten close to this crucial breakthrough but then I had given up. Readers didn’t seem to complain, but to me it was a glaring flaw.
> That deficiency has been corrected in this second edition. That’s why it’s some 70 pages longer. Yes, it’s a longer journey, but if you come along with me through the pages of this second edition, we shall dive much deeper into the internals of the CPU. Whether this will be a more pleasurable experience for you or not, I do not know. If you feel like you’re going to drown, please come up for air. But if you make it through Chapter 24, you should feel quite proud, and you’ll be pleased to know that the remainder of the book is a breeze.
So yes, some significant difference there, but maybe not worth a repurchase unless you just want it for your library or specifically want to read his take on that material.
