MacBook Pro 17", A1229, Mid/Late 2007, MA897LL/A, Board#820-2132-A

This board came with 2.4GHZ and 2.6GHZ processors.  The 17" aluminum Pro pads are especially hard to find because the board is so large, and the writing is so small.  Also of note -- highlighted in yellow are the additional "system reset" pads (which I admit I have not tried).
