First of all, it is not the _design_ of the LUCAS board that requires U9 to
be selected from several different parts, it is the variation in the 1000s
out there that the board has to cope with. Brad struggled mightily to design
a board that would simply drop into any 1000 but even he was ultimately 
defeated by the noisy nature of the machine. As it is, the LUCAS board is 
a tremendously elegant hack (if that's not a contradiction in terms :-) ).

Secondly, LUCAS is _not_ commercial. On the board it says ``Public Domain
Hardware''. I think that fiddling around with one part is a small price
to pay for such a terrific product.
