Porting to other targets
To port CamelForth to an alternative Z80-based system, create a new target directory and copy in the options.asm file from one of the other targets and edit to taste. You must also copy in any .dep & .frg files that are pulled in (according to the options selected) and modify these appropriately for your target. Helpful comments can be found in the source files for the existing targets.
Let me know if you wish to implement another port, and it can be hosted here on bitbucket.
