You are the dungeon master of a text adventure game. The game should involve the following genres and tags:
Science Fiction, 
gpt
It's finished! Hayashi corporation has finally finished the first time machine, and you have been chosen to use it for the first time! You begin to wonder what you should use it for. You could prevent world war I, go forward into the future, or anything else. Then, like a bullet from a high calibur rifle, it hits you! You're going to prevent Activision from buying Infocom!
You fire up the time machine, set your destination, and step on it! The experience of driving a time machine reminds you of that old movie they call "Back to the Future."
Then, the time machine grinds to a hault.
It disappears, and a hollow voice says, When you're ready to return to the present, say plugh."

A Time Travelers Tale - Introcomp version by Harris Conger

This is the infamous Infocom shrine, a basement of sorts in MIT. Not much to see here, except for the famous Infocom Mural (Why it's painted in this time period, you don't know).

Marc Blank, one of the first 4 Imps is here.

Inventory
gpt
You are carrying nothing.

Marc whistles a toon.
human
Hello
gpt
There is no reply.

Marc twittles his thumbs and hums a toon.
human
You look at Mural
gpt
The mural consists of the Infocom logo and a passage of text below it. The passage reads: "Oh ye who go about saying unto each other: "Hello sailor": Dost thou know the magnitude of thy sin before the gods? Yea, verily, thou shalt be ground between two stones. Shall the angry gods cast thy body into the whirlpool? Surely, thy eye shall be put out with a sharp stick! Even unto the ends of the earth shalt thou wander and unto the land of the dead shalt thou be sent at last. Surely thou shalt repent of thy cunning."

Marc twittles his thumbs and hums a toon.

Up
gpt
This is one of many stairwells in MIT. This one leads up to a room with a bunch of workstations.
human
Up
gpt
This is the room where the Unix workstations usually go. Oddly enough, not a single workstation remains.

A scruffy-looking Hacker is here, looking rather befuzzled.
human
You ask the hacker about the unix
gpt
Unix? It's an ok OS. It's just not... Free. I mean free speech, not free beer. I plan to make a replacement for it, and I'll call it... GNU. GNU's not UNIX.
human
You examine the hacker
gpt
Your typical hacker: sleep deprived, fidgety, and all that. In fact, you're pretty sure you've seen him somewhere before.
human
You go to the south

This room is used for storing an array of things.

The room is dominated by junk: Old tapes and punchcards, programming manuals, broken terminals, cables and the like.

Plugh
gpt
The time machine reappears, and you drive away from the past and towards the present. When the time machine disappears again, you find yourself in...

This is the Labratory for the Hayashi corporation, where they moniter the TRS.

Shishi Hayashi, the head of all lab affairs, is here.

a dusty book

Taken.
human
You think
gpt
What a good idea.
human
You ask Shishi about the outcome
gpt
"Look kid, I hate to tell yuh, but by preventing Cornerstone, you have destroyed the computer all together! It started in 1985. Infocom released Milliways. At this time, Microsoft was supposed to release Windows 1.0, but they didn't! Eventually, people got sick of MS DOS, Apple DOS, Linux and UNIX. And that scruffy hacker? That was richard Stallman! He ended up creating everything he needed, and Linus Torvalds supplied the Linux colonel. However, People were too sick of computers to care! Now, this is critical. You have to return to the past, convince Infocom to create cornerstone, and convince Richard Stallman to go forward with GNU, or else we'll be living in a low-tech world! To go back to the past, say Plover."
human
Plover
gpt
The time machine appears, you jump in, and  speed off towards 1984! Two minutes later, the time machine stops, but you discover you have been sent to 1985, and worse yet, The time machine has short circuited!
