At one time, a very useful website existed that was created to help people wanting to learn programming for the Commodore 64 and 128. It was called The Commodore Programming Wiki and was the brainchild of Scott Hutter.
Scott no longer has the free time to regularly maintain the project, but with his permission, I have adopted the project in order to keep this valuable resource available to those who might find it useful.
Although the format has changed, the valuable data will remain intact and will hopefully be expanded upon, as time goes on. If you would like to contribute to this guide, please feel free to contact me.
I hope you find this information as useful as I do.
