Yea, even in the 80s when I was in school, the CS department switched from
running the HW simulator on the HW in question, and we had to write
everything
to bring up the HW on the DEC-20 (well, simplified DEC-20) to linking in
your code
to the SunOS kernel on the 68k Sun3 machines that were plentiful and doing
the
debugging on real hardware. I'm not sure there's a lot of students that
have done
a full, from scratch, bootstrap of a real OS (or even a Toy one) these
days...  Though
a lot of activity there has shifted to the cheap embedded world where it's
easy to
write a bare-metal app that has many of the features of an OS, but in some
weird,
specialized way.
