we are currently very close,to bring a systematic strucure behind the latest PB resisitor locations.Folks with a 1.33Ghz (7447type) can already upclock to 1.5 but we need help to get the last steps- overclocking to 1.83 and even 1.92Ghz. What we do have yet: scans of the sensible areas of the 1.33, 1.5 and 1.67 17" PB Now we need a genius to bring those resistors in perspective with the official Motrorola PLL charts, so we know which resistors to move to get past 1.67Ghz. All the relevant info is at the end of the comments.
