IBM ThinkPad Dock II
The IBM UltraBase X2 is a portable dock for the X20 to X24 series ThinkPads providing extra ports as well as the originally missing drives and a set of stereo speakers. Together with the ThinkPad it forms a solid unit approximately double the height of the ThinkPad alone. Containing a builtin floppy drive and a full featured UltraBay 2000 slot, it provides flexibility in drive choice as well as the option of a secondary battery for extended working time on the road. The UltraBase X2 doesn't provide a second docking port as the original UltraBase did, hence you can't dock the UltraBase to any of the other docking solutions.
