Old computers often fail at the boundary between a proprietary part and the rest of the system: unusual displays, storage buses, power supplies, video outputs, or fragile flex cables.
Open replacement hardware works best when the repository includes the research trail, connector data, verified source, and manufacturing evidence—not only a product listing.
Systems catalog
The systems catalog lists consoles, handhelds, and home computers that still have a third-party hardware scene. Each popular mod is marked open source or proprietary. Open-source repositories get generated project pages.
