Received as a gift from my piano teacher a while back, who said it used to belong to her son. At the time, I didn't know anything about the arcade legacy of Centipede or Millipede, but I held onto it, assuming it was some sort of rare find that I could sell for hundreds or even thousands of dollars someday. Many years later, I sold it to a game store for a few bucks just so I could get rid of it.
