[[!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Only the features that were not superseded are listed.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.
