Board Scans - Set 1
This set is an older revision of the logic board compared to Set 2.
 * The GND pin (10) on LS245 @ N2 is not connected. Its somewhat uncommon but this causes some sounds to have/be static.  The GND pin is properly connected (underside of logic board) on the newer revision.
 * Additional difference may exist

Scan Notes
 * The battery and BIOS chip were removed.
 * Any metal stand offs seen around the edge of the boards were use to level the board for scanning.

Board Scans - Set 2

 * The battery and BIOS chip were removed.
 * Any metal stand offs seen around the edge of the boards were use to level the board for scanning.

Board Scans - Set 3
This set is a newer revision of the logic board compared to Set 2.
 * There is a ground trace that was removed on the bottom side of the logic board, under the 24Mhz crystal. You can see someone manually cut the trace if you look at it in Set 2.  I believe this was removed because of a grounding loop.
 * Additional difference may exist
