The Card Dock is an all-in-one alternative to the modular docking system. Its wealth of features - from 32-bit PCI bus technology and serial, parallel and PS/2™ ports, to twin USB ports, audio in and out, and a PCMCIA-compatible PC Card slot for Type III or Type II cards - will help you make the most of your Tecra 8100 notebook. It includes a slot for a Kensington cable lock (which also protects the PC Card slot), as well as an auxiliary lock to secure your notebook in the Card Dock.
