Abstract: A computer system comprises a storage device comprising a plurality of locations for storing data and having a defined audit partition region comprising one or more of said locations and processing circuitry for detecting access requests to alter data on respective sets of one or more of locations of the storage device. Responsive to each access request, the processing circuitry stores data from said respective set of locations in the audit partition region prior to performing the access request, such that a sequence of data transfers from the storage device is stored in the audit partition region in a known order. Responsive to a user request, data is restored from the sequence of data transfers in the audit partition region to the respective set of locations on the storage device to return the storage device to a previous state.

Abstract: A coin operated golf type game in which the player strikes a golf ball with a golf club and drives the ball up a ramp to a target area having scoring holes through which the ball may drop. The ball returns along a track system to a ball collection point and during the course of its travel actuates the various scoring devices which illuminate the scoring board, and sounds bells or horns in accordance with which scoring hole the ball has entered. Both positive and negative scoring increments are used. When a predetermined number of balls have been played, the game scoring is automatically terminated and an indicator lights showing the scoring proficiency of the player. If a sufficiently high score is achieved, the player is awarded a free game.
