Duo Floppy Adapter

The Macintosh PowerBook Duo Floppy Adapter (informally referred to as a MicroDock) is a lightweight portable docking device that was developed by Apple Computer and released on October 19, 1992, along with the PowerBook Duo 210 and 230.
==Features==
Though much smaller than the Duo MiniDock, the Floppy Adapter still interfaced with a PowerBook Duo notebook through the custom 152-pin docking connector. Instead of a motor or lever, a small button was used to release the device. The only ports provided were a single Apple Desktop Bus (ADB) port and a HDI-20 port to attach an external floppy drive.20 Macs for 2020: PowerBook Duo by Jason Snell, Six Colors. 2020-08-10.Apple Duo Dock pinout, Pinouts.ru. 2017-05-30.
