I've seen pages documenting this, but that was
years ago. The chip
sales sites (for companies who may or may not actually HAVE the chips
they're trying to sell, grumble) have certainly swamped that stuff, as
you've found. I suggest progressive google search refinement to find
the right stuff, as I know it's out there.
There is an add-on for firefox that you can isolate entire sites or
sections of sites on google search. I use it at home, in my desktop.
Unfortunately my desktop is still stored (I may remember you I just moved to
Sao Paulo). But I'll try to look for it this week
