Yes, we were selling solutions.  For some time there was a discussion about 
making an off-the-shelf b16 part (and we even had a summer student project 
evaluating the feasibility of a C compiler), but marketing told us that 
selling solutions is way more profitable, so we shouldn't waste our time 
competing with 50 cent parts.

The competitor for the last project uses an MSP430 for their solution.  Also 
a good choice for the problem at hand; especially since they program in C.  
But they need a lot more code memory, making it more expensive (Memory is 
cheap.  Less memory is cheaper).

In general, selling complete solutions is more profitable than selling 
components.

BTW: The evaluation of trying to map a stack-based C compiler output to b16 
was quite promising.  The student did just dump out the intermediate 
language, and wrote a small program that generated b16 assembler from that, 
instead of using the generic backend.  He struggled a bit with the b16 
assembler, which has no labels, but structured conditionals.  A C-optimized 
b16 however should have a dedicated pointer register which can read and 
write with some small offsets (5 bits are enough).
