Learning 6809 assembly language #VintageComputing #Programming
PWILLARD.COM dives into programming 6809 assembly language with tools available for modern computers.
If you’ve never tried to write 6×09 assembly language programming for the Radio Shack Color Computer before, now it’s easier than ever before. While you can use a native editor assembler, like Robert Gault’s 6×09 updates to Tandy’s DISK EDTASM (which is excellent), it’s probably a lot simpler to just write the code in your favorite editor and then use a cross-compiler such as LWASM to assemble your code on your PC.
You can then use programs from the cross development TOOLSHED to copy your local binaries to a virtual floppy and test your work on one of the virtual color computer emulators such as Xroar, VCC or MAME.
The article here also goes into learning 6809 assembler.
