Brian,

   You're off to a good start with kprintf and kputc.  The rest of the advice
is common sense: add one device driver at a time, testing as you go.  Lot's of
people boot Xinu from ROM or upload it, so that shouldn't be a problem.  You
might be able to squeeze it into EPROM (V7 on the LSI fits into 56K bytes,
and that includes data, bss, and stack).

   As for giving it away, that's fine.  You can even charge for a product
that contains Xinu as long as you charge only for the other parts and
not for Xinu itself.

   Is the SANDPAC board generally available? How much does it cost?

   What speed will the radio links support?

Regards,
Doug
