I agree, it's better to sum up a little what the thread is all about.
Since I downloaded the PDF, I'll do the sum up, it's a work in progress paper written by someone who is reverse engineering the X360. Only the CPU pinout, according to the author, and a short conjecture on the potential presence of the
eFUSE technology in Xenon are on this paper for now, though.
The author says he'll keep it updated.
