Abstract: A powder down door open memory latch circuit for a gaming device which determines whether a door on the gaming device has been opened during a power failure. The circuit includes a cam switch coupled to a lock on the door of the gaming device, the switch being actuated to provide a signal when the door is unlocked. The circuit also includes a hinge switch mounted adjacent a hinge connecting the door to the cabinet of the gaming device to provide a signal when the door is opened. Each of the switch signals is coupled to a respective battery powered memory latch to cause the latches to change from a cleared state to a second state when the door is unlocked and open. Upon the restoration of power after a powder failure, the main processor for the gaming device determines the states of the latches and if the memory latch states indicate that the door was unlocked and opened during a power failure, the processor tilts the gaming device to prevent further operation thereof.
