The Lego RCX uses a special byte code interpreter that was designed to 
work in the Lego environment.  The last time i checked, the Ada subset 
compiler for the RCX really generated NQC (Not Quite C, a C subset 
invented by David Baum to program the RCX).  NQC compiles down to the 
byte code used by the RCX.  Perhaps the latest version of the 
Ada-to-RCX compiler does the same thing.  However, since the firmware 
that runs inside the RCX is proprietary, and the license only allows me 
to copy it to my RCX, and the environment would undoubtedly be 
different if i used an SH-8...  I'm not sure i can get to where i want 
to go by that route.

It would be an interesting project to create my own Ada-subset compiler 
for a microcontroller, but i just don't have the time.
