Newer Technology MicroDock

The Newer Technology MicroDock is series of lightweight portable docking devices that were marketed by Newer Technology for the PowerBook Duo line from Apple Computer.

Features
Based on the design of Apple's Duo Floppy Adapter, the MicroDocks interfaced with PowerBook Duo notebooks through the custom 152-pin docking connector. Instead of a motor or lever, a small button was used to release the device. Each MicroDock included a single Apple Desktop Bus (ADB) port along with the following, depending on model:
 * Color MicroDock: port for 8-bit color video and 3.5mm audio jack for external speakers.
 * Ethernet MicroDock: 10BASE-T Ethernet port.
 * Floppy MicroDock: HDI-20 port for an external floppy.
 * PC Card MicroDock: Slot for a PCMCIA card.
 * SCSI MicroDock: HDI-30 port for external SCSI devices.

Support
The MicroDocks are known to support all PowerBook Duo models, but Ethernet support requires the installation of software drivers.
