Why, it's Leslie, a Leslie speaker, and it had two spinning parts, one in the bottom and the spinning horns on top.
Edit: Here is an explanation:

There also used to be as much voodoo with micing a Leslie as micing a snare drum. Such as one mic top and bottom, one mic bottom and two mics top (some times one with phase reversed) Mic the open back, Oh no, mic the louver side, better Doppler effect. Well, you get the idea.
Hard to tell from the video - it could be almost anything. My dad used to hook up all kinds of gear to his setup. Might be for one of the other keyboards. Probably just dead weight to keep that thing from propelling itself into outer space!To add further to the questIon. what do you guys think is sitting on top of the case. @ 5:14?
