I have done some homework...
The Overview page for the port replicator is:
The original design for the firewire port on the replicator is for DVI: Digital Video Input.
Unfortunately, the DVI port only works with A2*p systems (and I have an A20m--DARN!!!)...
So that pretty much ends it for me...but for those of you with A20p's or other compatible thinkpads, I'm curious to know if it's possible to use the DVI port to connect a storage device like an external hard drive...?
In any case, i'm now looking for another way to connect my external hard drive to my thinkpad through firewire (like perhaps a PCMCIA card?).
Any suggestions in this regard would be appreciated.
Thanks for your time.
