Master computer

A component than can replace all Command and Control components on a ship. The description says it is an AI, but not to worry, a ship with a master computer is no worse (or better) at obeying your commands than a ship manned by living crew.

A ship with a master computer (whether intact or damaged) is immune to attack from the Allegiance Subverter. It can be destroyed by a computer virus. The master computer is not immune to a boarding party, they must be carrying bootable floppies in addition to antipersonnel guns. The intelligence project, crew insurrection can still capture a ship with a master computer.

The master computer may take up more space than the other command and control components. At least for low tech levels and smaller hulls. It is also much more expensive, so maintenance can be a surprise if you decide to build your fleet around them.
