There were metal roll-around carts sold to schools that held 20 some of the second generation ibooks, each in a holder where they latched into place. The standard power supplies fit into the back of the holder, and the power plug was held where it mated up when the ibook was inserted. There was one at each of the four local schools that were purchased when those white dual usb ibook models (g3/500) came out.
