Starcross

From Wikipedia

Starcross is a 1982 interactive fiction game designed and implemented by Dave Lebling and published by Infocom. Like most Infocom titles, it was developed for many systems. It was released for DOS, as a PC Booter, Apple II, Atari ST and Commodore 64. It is Infocom's fifth game.

The game was Infocom's first in the science fiction genre. It takes place in the year 2186, when the player's character is a lone black hole miner exploring an asteroid belt. The player's ship, the Starcross, is fitted with a mass detector to look for "quantum black holes", which are such powerful sources of energy that one could provide a wealth of riches. When the mass detector finally discovers an anomaly, however, it isn't a black hole but something else entirely: a massive craft of unknown origin and composition.

The player must dock with the mysterious ship and gain entry to its interior. Once inside, the player discovers a wide variety of alien plant and animal species and an array of unfamiliar technology.
