Duo MiniDock

The PowerBook Duo MiniDock (originally released as Macintosh Duo MiniDock) is a portable docking station that was developed by Apple Computer with SuperMac Technology and released on October 19, 1992, along with the PowerBook Duo 210 and 230.
==Features==
Like the full-sized Duo Docks, the MiniDock interfaced with a PowerBook Duo notebook through a custom 152-pin docking connector. However, instead of a motor, a lever was used to secure and release the devices. All the ports, drives, and expansion slots of the dock would become accessible by the PowerBook Duo as a NuBus device. It contained 512KB of video RAM that could support up to 8-bit color on a 832 x 624 external display, while the built-in LCD was operating simultaneously.20 Macs for 2020: PowerBook Duo by Jason Snell, Six Colors. 2020-08-10.Apple Duo Dock pinout, Pinouts.ru. 2017-05-30.
===Variants===
The MiniDock was manufactured for Apple by SuperMac Technology, which also released its own version, the EtherDock under its E-Machines brand.E-Machines EtherDock for the PowerBook Duo series by Sean2300c, RetroMacCast. 2009-01-05.
===Issues===
With repeated use of excessive force, the plastic ejection lever is known to be prone to breakage. A PowerBook Duo that is connected to a MiniDock cannot sleep while an external monitor or SCSI device is attached.Dockのスリープ時の脱着 (Japanese) by まーくん, Linkclub. 1998.
