Some M6800 assembly language and some python code to make SWPTC play wave data!
This code accompanies a video where I made a sound card using Bob Applegate's design located on GitHub here

Feel free to comment on the video and ask questions. I will try to answer any questions on usage etc.
To run the Python Notebook you need to install Jupyter Notebook. Instructions can be found here https://jupyter.org/install
You will also need a few python libraries. Here is how to install them
pip3 install numpy matplotlib soundfile samplerateAssembly language was complied with AS02.EXE written by Frank A. Kingswood. A link to the assembler compiler is here http://www.kingswood-consulting.co.uk/assemblers/
The following command will output a S19 file but you need to add the text S9 at the end of the file on a line by itself so that it loads seamlessly into the SWPTC 6800
as02 -l -c -s -v play68-pwm.asm
