I wondered what the wheel was for

The inner wheel was for fine tuning the crystals.

The outer wheel was used to keep the roller-mounted
computer room, which had a tendency to gravitate
to magnetic north, oriented to true north.

The TV was used to make sure that you didn't back into
a tree while doing so.

Not sure about the guy in the suit. He's either Leonid Breshnev
or Harland Sanders without the beard and moustache.
