[[!meta title="The Attic Museum"]] Over time, several kernel components were removed from NetBSD, often because they were too hard to maintain, not always functional, and because the features they implemented were not particularly wanted anymore. This page provides a list of these removed components, with references to the original code. Only the features that were not superseded are listed. Each component used to be maintained and functional, but over time became broken because of lack of interest and inability to test changes, especially on old hardware and ABIs. An estimation is provided of the NetBSD release believed to have had the most functional version of each feature, before the feature started deprecating. Note that this estimation may not be totally accurate.
