@jemo07 @deirdresm @kkarhan I started a Forth in RP2040 assembly mostly because I wanted compatibility with the mountains of C and C++ libraries for the device and its ilk. I have the kernel working but there are faster bare metal Forths (Mecrisp and Zeptoforth) and I will get the portability I want from #CForth.
Also, there's a renewed interest in #FPGA #Forth implementations. I know of at least two active ones, both open-ish source.
