It seems like an awful lot of work to fabricate what's already there?! Get a small traveling optical mouse and a foldable membrane keyboard (which for my money has better "feel" and less "rattle" than the PDA units, is cheaper and packs easier with less space as well) or get a PMCIA card USB hub and use USB accessories - an even cleaner, less bulky setup. This all works well in my L110 with Win2K. I'm just waiting for the foldable membrane 15" LCD draped over my knee to add to all of this.....#8~} Chester ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://www.silverace.com/libretto/ - Archives -------TO UNSUBSCRIBE------- Reply to any of the list messages.
