I own a number of evaluation boards for different cplds & fpgas coming
from ALTERA and XILINX and yes even one from ACTEL. However, none of
them has exactly the combination of things in the right measure onboard
as I think the Darnaw has. Only very few things have to be breadboarded
externally. Thats why I am thinking about making the Darnaw my "internal
standard" and design my applications around them.
