I apologize...I should've checked in another browser (works in Chrome, w/o cookies) and/or mobile...not being sarcastic here, I've never been quite sure how stable Google Books's permalinks are outside of Chrome. But yes, the submission is meant to point to a specific chapter about Carmack growing up and acquiring an Apple ][
For what it's worth, it took me to the appropriate page in Firefox as well.
I think it might be based on location (UK here), it doesn't link directly to a page in any browser I tried.
