Hello, I believe only 50% of the Arduino Mega flash is available to Forth for dictionary use. This is simply a hardware barrier that exists. The additional 126kb theoretically can be put to use in other ways, but I've not seem actually solutions. On Sun, Apr 17, 2022, 2:48 PM Tristan Williams wr

The big advantage with the Arduino Mega is lots of 8 bit ports available for parrallel i/o. The Arduino Uno pretty much forces all i/o to be serialized one way or another. On Sun, Apr 17, 2022 at 3:33 PM Martin Nicholas via Amforth-devel < amforth-devel@lists.sourceforge.net> wrote: > On Sun, 17
