I remember spending hours on the Amiga trying to understand how to play Carrier Command. The woes of pirating games, not having a manual. Here's how the repair system looked like:Long before Elite Dangerous I thought we should switch to a system inspired by Carrier Command which had fixed equipment that could be damaged individually.

Looks similar to Silent Service II, where you also had independent parts of the sub that could be damaged.
