You might want to look at MForth, source code is available. It's a fast ANS forth and runs from ROM.
You could use it to find the info you want to port fig forth or even better, if you have a REX or rom burner, extend it. It would be nice to have some more wordsets or a maybe compiler to produce stand alone CO files that could be distributed without the ROM. http://www.strangegizmo.com/products/mforth/ -- John.
