Justice League data-processing machine

The Justice League Computer's Justice League data-processing machine is a device in the Hall of Justice that the Justice League use to process data.

Superman used it to analyze a piece of paper that was sent to them by Marvin. He was curious if the schedule shown on the back of the not was airplane, train or steamship arrivals and departures. When he put the paper into the machine, he realized his theory was wrong, as the times shown on the schedule came back negative.
