Overview
For one particular production model MN-700...
 * "MN-700", "REV 3.0", "(C) 2003 MICROSOFT CORPORATION", and "P/N: 141400520001J REV: 01" is silkscreened onto the top (primary component side) of the board.
 * "MN-700" and "111362-30" is etched onto the bottom of the board.
 * While there is a clearly marked UART header, the UART and assoc. components are all omitted. It's presumed to be usable if populated. Hopefully..
