The Schematics are identical but the parts that are included are 
different. If you look on my Hermes page, you will find large format 
pictures of both TAPR build and Apache.

The most significant differences are those parts associated with Anan10 
and J15 on the Apache board.  The TAPR board is set up for Apollo and 
most of those differences can be seen on the bottom view of the TAPR on 
my web page. The parts on the bottom are not included on the Apache 
version and K15 is not included.  TAPR also has never released an "as 
built BOM" for comparison.
