Below Level Seven

1. You've been to the Gym, haven't you?
2. Read the sign in the gym.
3. You can find a jammer in the dark storage room near the Workshop on Level Five. You'll need the headlamp to see in the storage room.
4. To stop the exercise machine, the jammer must be turned on, and it must be set to 710.
5. Oh yes, one other thing. Have you examined the jammer?
6. Have you seen anything that might fit those twenty tiny sockets?
7. Plug the twenty-prong fromitz board (from the Astro Lab) into the jammer. This will disable the exercise machine.
