Abstract
A computer system comprising a personal computer assembly (motherboard), memory for storing data, means for detecting loss of applied power, and means responsive to the detecting means for inhibiting data transfers by the processor of the personal computer and the memory. In accordance with the invention, memory comprises non-volatile memory and the inhibiting means applies a signal to the memory to inhibit data transfer operations of the memory. The means for detecting loss of applied power detects loss at a power mains connection of a power supply for supplying operating power to the personal computer assembly. A machine control comprises a computer system according to the invention.
