'''Minerva''' is a reimplementation of [[Sinclair QDOS]], the built-in [[operating system]] of the [[Sinclair QL]] line of [[personal computers]]. Written by [[Laurence Reeves]] in [[England]], Minerva incorporates many bug fixes and enhancements to both QDOS and the [[SuperBASIC]] [[programming language]]. Later versions also provide the ability to [[Computer multitasking|multi-task]] several instances of the SuperBASIC interpreter, something not supported by QDOS.

Minerva was distributed as a [[read-only memory|ROM]] chip on a [[daughterboard]] which replaces the QL's original ROM chips. A Minerva Mk. II daughterboard also incorporates an [[I²C]] interface and non-volatile real-time clock. As of version 1.89, the Minerva [[source code]] is licensed under the [[GNU General Public License]].

Other reimplementations of QDOS include [[Small Multitasking System 2|SMS2]] and [[SMSQ/E]].
