Hi @zbyti - my long term plan, when I have free time (currently very limited) is to map the file i/o to the Forth BLOCK words and also create some words to use the graphics capabilites of the Neo6502. Unfortunately, the default graphics mode of the Neo6502 doesn't lend itself well to a standard Forth 64-character wide x 16 row "screen editor" because the screen is only 53 or so characters wide. I haven't played around with reprogramming the RP2040 to output 640x480 text mode instead, but that's one possibility. If you make any other changes/additions for the Neo6502, feel free to send another pull request. If I ever get around to working specifically on this platform, I may need to move the starting address back a bit if I need more room for code.
