Abstract
A method and apparatus for rapid interconnection (hot plugging) peripheral device interface circuits to a computer bus is disclosed. The interconnections are completed using three sets of conductors in the sequence: common grounds, power from the bus and data lines. The time period between the interconnections is determined by the relative set back lengths of the conductors from the card edge and allows for stabilization of voltage and establishment of a stable high impedance state for the peripheral device controller circuits before the data lines are interconnected.
