Please Help Me

Help the person on the other end of the machine get free.

The opening of the game:

You find a small black box with a keyboard and a little screen buzzing and flashing at you. When you pick it up, you see the numbers "1979" scratched into the black plastic. You also see a message printed out on its screen:

Hello? Is there anyone on the other end of this?

Please.

I don't know where I am but I found this thing that sends texts.

Is anyone there?

Can you help me?
