Are the Nintendo Lodgenet systems built-in to the television sets? I was wondering because I came across a thrift that has probably ten TVs with Nintendo Lodgenet controller holders attached on their tops, and the TVs have what look like a phone plug in back (I remember the N64 Lodgenet controllers having a phone style plug) in addition to the standard connectors. I was curious if the gaming hardware was inside. I'm not a Nintendo collector, but it makes me want to crack one open to see what's in there.
