ok. I couldn't help myself. I know David has a near hayes/ANS compliant forth for fuzix, but I went ahead and rolled my own anyway. I simplified my forth cross compiler (written in C) so it would work in fuzix. The compiler spits out assembler for as09 to compile. The source file for the compiler was fully written using "levee". I have the ability to make immediate words, so technically the cross compiler's job is done, and the rest can be programmed in the target forth itself :) This should make it handy to really test out Kernel calls interactively.
Cross Compiler: 14k bytes
Cross Compiler source: 4k bytes
Resultant Forth: 2.5k
