Matthew Paul speculates that if he put $100 in the bank then traveled 100 years into the future, "the interest alone would make you a millionaire."

In the opening sequence, Nick reaches into the plane with his left hand to retrieve the floppy disk. He retrieves the disk with his right hand, but when Nick pulls his hand back out, the disk isn't there.
In initial shots, the time machine's computer is a Commodore 64 with a 1541 floppy disk drive, which is also generates the screens and provides voice synthesis. Later on, it changes into a Commodore Amiga 2000, complete with separate keyboard, which was previously in Nick's living room.
Nick steals a car to escape the Gen-Cor guards. The car crashes into a pile of bikes and flips over on its side. As it tips over, the device used to make the car flip sticks out of the bottom of the vehicle.
