See a very rare electromechanical slot machine from 1940 in operation. This machine takes 5 cents and spins five reels allowing the player to play draw poker, by holding some cards for a 2nd draw if the first draw is not a winner. We have all seen this very same game in early video games of early 80's. But there is nothing electronic in this one, still it plays the same :-)
Machine has an hidden drawer for payouts, typical of console machines of this era.
