-A1- POWER SUPPLY FOR COMPUTING MEANS WITH DATA PROTECTED SHUT-DOWN Abstract of the Disclosure A method and apparatus is disclosed for protecting data being processed by a computing means upon the occurrence of either a power fault condition or an intentional shut-down initiated by the computing means. In the former case, the power fault condition is sensed and provided as an anticipa- tory fault status signal to the computing means which immedi- ately executes a data protect routine to store data presently being processed. Subsequently, the computing means issues a shut-down command to the power source. In the latter case, the computing means initiates a shut-down command but executes a data protect routine prior to the shut-down command. In both cases the computing means is itself connected to the power supply and governs power shut-down.
