I have a new post on Hackaday: MilliForth-6502, A Forth For The 6502 CPU.

Some material was deleted by the editors so I have included it below for the archive.

The main code is the assembly code in sector-6502.s.

These are the commands I ran to take it all for a spin:

mkdir /tmp/milliForth-6502
cd /tmp/milliForth-6502
 
git clone https://github.com/cc65/cc65
cd cc65
make
sudo make install
cd ..

git clone https://github.com/ShonFrazier/lib6502
cd lib6502
make
sudo make install
cd ..

git clone https://github.com/agsb/milliForth-6502
cd milliForth-6502
touch out
source do1 sector-6502
wc -c sector-6502.out
hd sector-6502.out
