Abstract: In a computer system having a configuration which is subject to change, because of failure replacement, updating, or expansion, it is necessary to provide means for loading parameters carrying the present system configuration into the active modules of the system. In this manner, all parallel processors are identified and recognized and depending upon system demands, used because of the parameter loading arrangement of this computer system. Serial lines are provided for loading the parameters into the active modules.

Abstract: In order for any failure of the power supply unit for two read-write memories which are operable in parallel, not to result in irreversible damage to data, two parallel power supply circuits are provided for the operation of the memories. Each power supply circuit is capable of supplying the operating current of one of the memories and the standby current of the remaining memory. Each of the power supply circuits in the power supply is buffered with capacitors in such a manner that, upon a fault in one of the power supply circuits, the output voltage, as soon as the capacitive buffer declines from a normal operating voltage to a threshold voltage and to a minimum operating voltage, data secure current reducing steps are taken.
