Every item is for either your Commodore PET, VIC-20, C64, C64c, SX-64, C16, Plus/4, C128 or C128D. Every product is currently commercially available or coming soon. That means that while you browse this guide, if you see something cool you can order it and have one for yourself.

The items are grouped into 12 broad categories and subgrouped thematically to help you find that expansion for your Commodore 8-bit that you never even knew existed, without first needing to know who makes or sells it.

Some items have feature pages, and more feature pages will be added over time. A feature page describes the primary function and use of the product, shows up-close photographs, lists the models of Commodore it is compatible with and links to the product's homepage and documentation. It also lists prices and gives clear instructions about how you can order it. The feature pages open up comments for the community to leave reviews, and to ask and answer questions.
