Abstract

An operating system for a gaming system includes a data producer which generates non-reproducible data relating to a transaction carried out in respect of the gaming system. A data consumer is in communication with the data producer for storing data relating to the non-reproducible data. A game controller is in communication with the data producer and the data consumer which effects communications between the data producer and the data consumer by means of a transaction-based protocol. The invention also relates to the use of data storage device for a gaming system that includes a local power supply.

23. The method of claim 22 which includes, when the transaction message is received by the game controller, updating a memory of the game controller.

24. The method of claim 23 in which the data consumer is a meter of the gaming system and in which the method includes using the game controller to calculate new meter values for the data consumer.

25. The method of claim 24 which includes creating a new transaction message, incorporating the same transaction-ID and producer-ID, at the game controller and forwarding the new transaction message to the data consumer to update meter values in the data consumer.

26. The method of claim 25 which includes, after processing of the message, returning an acknowledgement message, with the same transaction-ID and producer-ID, from the data consumer to the game controller.

27. The method of claim 26 which includes passing the transaction-ID and the producer-ID in the acknowledgment message from the game controller to the data producer at which the event occurred.

28. The method of claim 27 which includes deleting the original non-reproducible data from a memory means of the data producer when the data producer receives the acknowledgment with the same transaction-ID from the game controller.

29. The method of claim 20 which includes using a USB protocol as the transaction-based protocol.

30. A data storage sub-assembly for a gaming system, the sub-assembly including:

a data store for storing data relating to non-reproducible data relating to a peripheral device of the gaming system;

a transaction processor for processing the non-reproducible data relating to the peripheral device of the gaming system; and

a power status indicator for providing an indication of power status to the transaction processor.

31. The sub-assembly of claim 30 which includes a local power supply unit which receives power from a main power supply unit of the gaming system, the local power supply unit including the power status indicator for providing data relating to power status to the transaction processor.

32. The sub-assembly of claim 30 in which the data relating to the non-reproducible data includes information relating to an unique transaction identification means and an unique peripheral device identifier and, when the transaction processor receives a message relating to a transaction effected by or at the peripheral device is received the transaction processor uses the information to determine if that message had previously been received and the data contained in that message stored.
