docking station compatable with T23 & T30?

[winslow]

which docking station is compatable with both the T23 & T30. Anyone have experience here?

[SMA]

T23 and T30 share the same docking stations and port replicators.
That is, you cannot find an IBM docking station or a port replicator that will support one of the machines and not the other.

Docking Stations
ThinkPad Dock (type 2631)
ThinkPad Dock II (type 2877)

Port Replicators
ThinkPad Port Replicator
ThinkPad Port Replicator II
ThinkPad Mini Dock (type 2878)

I assume that you mean something which can support an Ultrabay 2000 device and has room for a half-sized PCI card. If so, then these docking stations will do:

If all you need are the simple ports (ethernet, audio, modem, serial, parallel, video, etc.), then these port replicators will work:

edit: Beaten by SMA; late to the game as I was taking care of one of my cat's messes... BTW, the II versions can handle T4x systems and most R4x and R5x systems as well.
edit2: Clarification on the docking stations and port reps... The docks have their own built-in power supply. Simply plug in the AC line cord and you're good to go. The port replicators use the regular Thinkpad AC adapters but be careful since some of them require the G40 AC adapters; the ones with 4-pin plugs as opposed to the "barrel" style seen with T2x and T30 systems.
