Something at least a little like source is available directly from the
machine.  Try using the "see" word, as in,

ok see probe-scsi

which will show you what the probe-scsi word's code looks like.

It doesn't always produce anything terribly useful; in particular,
sometimes you get stuff like

: foo is
  (f042a800) 2dup (f0421780) if
    (f041ffc0) (f0425578)
  then
;

and to drill down through that kind of stuff you need to look at the
implementation of see itself

ok see see

and use its internal words.  It's kind of like what I've seen called
"shrouded source code" when it's applied to more traditional languages,
and it has most of the same benefits and disadvantages.

Whether this is any help to you is another question.  You probably
could figure out what you want this way, but it would take a good deal
of groveling around and piecing things together.  It would help if you
really knew FORTH, so picking up a book on it is strongly indicated.
