He has a package available for free download.  There are links to it
in a couple of the blog posts.

I don't have source code for the compiler itself, so there are no
changes to that.  Trust me, if I had source to the compiler then I
wouldn't be running it under DOS!  :-)

There are, of course, some changes/additions to the library and
startup code to enable building CoCo-compatible binaries.  It is hard
to balance detail with readability in a blog post, but there are some
descriptions in the various posts about startup code modifications,
support for building interupt handlers, etc.  If you want more detail
then you'll probably have to wait until I can scrape together something
to release.
