Strangely, this machine doesn't seem to have any visible connection for an energy source, at least not on the surface. It's completely embedded in the wall. Perhaps there are wires within the basement walls, but nothing is visible on the outside.
There are four digit input boxes on the display, two in front and two at the back, with a numeric keyboard below. Something seems off; after all, this portal was used as early as the 1970s. Jack Chambers traveled to the Dark Tower World through here. After so many years, why is it still displaying content? What's its energy source?
Jimmy: "Is this it?"
Roland nodded: "Input the world number, and you can directly teleport to the Dark Tower World."
Jimmy: "What if I input other numbers?"
Roland: "I don't know. I haven't tried many."
Jimmy looked at Roland: "So, are you leaving now?"
Roland was silent for a moment, "Yes, once I buy some things, I can leave. Jimmy, are you really not going with me? Just need to confirm."
