Connector: JAE part number JX20-152BA-D1LTH

Provides the interface between the PowerBook Duo computer, and the Duo Dock. It mounts directly to the Duo Dock's main logic board, and plugs into the matching connector on the PowerBook Duo rear panel, giving the Duo Dock direct access to the microprocessor's 32-bit address bus, 32-bit data bus, and control signals. It also provides access to power, control, and status signals in other parts of the computer, and allows the Duo Dock to provide power to the PowerBook Duo.
