E-Machines PowerLink Presentor

The E-Machines PowerLink Presentor is a compact portable docking station that was developed by SuperMac Technology and released in 1993 under its E-Machines brand for the PowerBook Duo line from Apple Computer.
==Features==
Smaller than Apple's Duo MiniDock, but larger than the Duo Floppy Adapter, the PowerLink Presentor 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 ports provided included a single Apple Desktop Bus (ADB) port, a HDI-20 port to attach an external floppy drive, a 3.5 mm headphone jack for audio out, and a and for video out. The RCA connector uniquely allowed PowerBook Duos to be easily connected to analog CRTs or projectors that were commonplace at the time.拡張性／ドック類：何のためにドックは必要か？ (Japanese) by Nao, Duo-Zone Kansai, FC2. 2005-05-23.Apple Duo Dock pinout, Pinouts.ru. 2017-05-30.
==Supported models==
The PowerLink Presentor is known to support all 68k-based PowerBook Duo models, though its compatibility with the PowerPC 601-based PowerBook Duo 2300c is unknown.
