Commodore 64 Screen Codes

Post Archive Icon

The new format of C64OS.com has opened up an exciting new possibility for me. With the new dedicated weblog section of the site, and its left sidebar, I can now pin feature posts to the top to make sure people who randomly visit the site will discover them.

But the sidebar actually now gives me a place to open up a whole new categorization system. I am always looking around the web for the various programming references and documentation that I need. Now, I can make blog posts that contain key programming reference material, and simply tag those posts "Programming Reference". And the sidebar can display a list of posts so tagged. Boom, instant access to all my most frequently used reference materials available in one place.

I hope this post series will be useful to other people too.
