Power-up sequencing apparatus
First Claim
1. A power-up sequencing apparatus for successively energizing a plurality of associated subsystems in a host system, comprising:
- a series of interconnected sequencing circuits, each said sequencing circuit interconnected with a subsystem and including;
first switching means, responsive to an initial system power-up, for disabling its associated subsystem;
second switching means, responsive to an initial system power-up, for suppressing the start command to the next sequencing circuit in the series; and
third switching means, responsive to a start command, for operating said first switching means to enable its associated subsystem and for operating said second switching means to introduce a start command to the next sequencing circuit in the series.
