Gordon, these many Forth implementations are more of a problem than a help. Which one should people try , evaluate, which ones will be supported in the future?
As such the foc commercial MSP VFX LITE versions for MSP430G2553 and for some ARM based Boards are well supported - not only for the maker scene - but as well for later commercial projects.
And Duncan uses this version for the MicroMouse Projects with his Warriors. http://www.micromouseonline.com/2018/04/10/minos-2018-2/
