SCO one told me on the phone (when I was contemplating SCO Unix/386) that they
would not sell their source, but that if they did, they'd charge around
$125,000.00 for it.

Minix is terrific.  It goes for around $80, not including the book (whose exact
title I forget) which is available separately for around $50.  Check the group
comp.os.minix for details -- there is a monthly post which gives the details.
Minix is a very good way to learn the basics about how the kernel works,
although it's not *really* the same.
