#myforth for the #8051 (http://www.kiblerelectronics.com/myf/myf.shtml) by Charley Shattuck and Bob Nash is the one of the few MCU #forth implementations I know of that takes a full minimalist approach: It is "inspired" by the GA144's ColorForth/ArrayForth.

The compiler & toolchain is in Forth (#gforth) as well as the firmware programmer (bootloader). Outside of initially getting the boot loader onto the target, there are no outside dependencies or tools (outside of Gforth).

I mention this because I am banging my head on the wall getting the myriad of GCC compiler & linker settings correct for my AVR128Dx project.

Between Charley Shattuck's #myforth on the #8051 (8-bit) and James Bowman's #SwapForth on his #J1a (16-bit FPGA softcore) and GreenArray's #arrayforth on the #GA144 (144 self-contained computers on a chip) and FORTH Inc's #SwiftX (#MSP430 and #STM32) and my own #toolboxforth (32 bits like ESP32, RP2040, as well as Linux/*BSD etc) I pretty much have all my embedded needs covered.

I've delivered systems using all of them, except for SwapForth, and I may indeed have a project for that....

Feeling in a very #forth mood today.
(And apparently in a hashtag mood too)
