Clyde has added some more FISHes to the repertoire. One for the NXP LPC1115 which has 8K of RAM and 64K of Flash. Plus updated versions (V1.6) of his previous LPC1114 Forths. All at the link.
And a version for the STM32F4 Discovery Board.
The general link for all his publicly available files is Clyde's FISH Forth.
This is a note on loading the LPC1115 FISH into an LPC1115 with Flash Magic. When it tries to verify you get an error message. Ignore it. I have a help ticket in with NXP, but so far they have not responded.
