Dear Ray,
there are some errors in your drawing of the Merger:
      1) the connector holes must have the same dimensions. This is not the case
         in your drawing because there are 6 wrong vertical positions of 
         the connector holes.
         I list them here:
     		   TS drawing             CHI drawing     
       		 (mm)    (inch)            (inch)
      		 21.8	 0.858		    0.873  
      	   	233.6    9.197		    9.182
      		238.6    9.394		    9.409
      		287.8   11.331		   11.316
      		292.8   11.528		   11.543
      		342.0   13.465             13.450
      2) Two holes for pcb mounting brackets: wrong dia. and hor.pos.
     		   TS drawing             CHI drawing     
       		 (mm)    (inch)            (inch)
       diameter   2.5    0.098              0.090
       hor. pos.  7.6    0.299              0.307

I spoke with Simone Donati: the modifications 1) and 2) must be applied
to the XTF-B as well.

About the lettering:
      3) the letters CE for the test point (over the CDF led) is
         missing.
      4) There are two "OUTPUT 2". The top one is "OUTPUT 1" instead.
      5) INFN TRIESTE should be "I N F N    T R I E S T E" that is
         with one blank characters between characters and some extra
         space between words.

I think it would be nice to have a prototype before going
to production.

      			cheers
