In anticipation of receiving the board, I went over the Bill of 
Materials that Tony had on the second schematic sheet.  A couple of 
minor discrepancies popped out:

1.  There are 4 4.7 uF caps specified in the BOM (C1, C3, C7, and C14.  
The schematic suggests that C1 and C14 are electrolytic (or otherwise 
polarity-sensitive),  However the BOM says all 4 are ceramic.  The 
board layout suggests that the BOM is correct.

2.  Under the capacitor listings, C7 is duplicated (both as a 4.7 uF 
and a 0.01 uF ceramic), plus there is no C6 listed.  However the 
schematic suggests that one of those C7s (the 0.01 uF) is actually C6.

3.  The BOM omits D1.

Can't wait to get the kit on board.  I'll be doing the LVDS version 
and, motivated by the excellent work of Leonard Leeper (KC0WOX) in his 
on-going documentation of the RXTX Build Process, will attempt to do 
the same for the Lite+Xtal 8.3.
