Well, if you want to learn "the heart" of FreeBSD, I think you'd be
better off working in C. The code that isn't part of FreeBSD on pretty
much every platform would seem to be disqualified as the heart.

So nobody else has them? You can't pick one up used on eBay? I
personally tend to run all but my most critical servers on
"discontinued" hardware. It's fast enough to do the job running
FreeBSD, and reasonably reliable; it's just not fast enough to run
modern versions of Windows. And I can buy a system and a hot spare for
a fraction of the cost of a new system.
