ThinkPad Port Replicator II

IBM ThinkPad Port Replicator II The Port Replicator II (Model # 74P6733) is the cheapest dock IBM sells. It contains basic pass-through connections for notebook ports, including power pass-through. It comes without integrated power supply but provides the same power jack as found in a ThinkPad, so you need to use either your Thinkpad AC adapter or another IBM AC adapter. Besides all the pass-through ports the Port Replicator II comes with an On/Off switch and a slot for a cable lock (only for the dock though). Features Passthrough ports: Ethernet (RJ45) Modem (RJ11) USB (1-port) DVI VGA Serial (DB9-M) Parallel (DB25-F) PS2-keyboard PS2-mouse Diskette drive Audio line-in and line-out Kensington Lock connector Power button Pros & Cons Positives: Inexpensive ($149 Retail) Negatives: Requires AC adapter, only one USB port, doesn't secure Thinkpad Compatibility: X20/30, T20/30/40, R30/40/50, and A20/30 series (Does not support X40/41, R40e/50e, or G40/41) Warranty: One Year IBM Website for Port Replicator II ThinkPad Docking Solutions HMM (February 2003) (248,638 Bytes) User's guide for the ThinkPad Port Replicator II and ThinkPad Mini-Dock (196,180 Bytes)

DVI pass-through

LCD monitors are getting larger and higher-resolution. Currently, DVI based on 165MHz TDMS transmitters can only (officially) support 1600x1200x32 at 60Hz, which is the resolution of your average 20" non-widescreen LCD. IBM's driver support for this resolution through DVI ports on docks has been inconsistent. Also in Linux you might experience problems even with this resolution and IBM officially states that the pass-through DVI port only supports resolutios up to 1280x1024. Read our page of information on how to solve these troubles.
