Make an Inference about Mr. King and his "cage".

Lets make an inference about Mr. King and this "cage" he has. Take a look at the text below! 

What was he pointing at? I took a step to the side and saw it at last, but I still didn't understand what I was looking at. There were blinking lights and a microphone, a bunch of black boxes with dials and knobs. It looked like a combination of a computer and an old-fashioned radio. "What is it?" I asked after a few seconds.

Make an INFERENCE about the cage using clues from the book and your background knowledge.
