Hey, congrats on getting the TX16W. The Typhoon OS really turns these into great samplers.
I'm surprised to find that the download links at NuEdge are no longer available. Seems it slipped under Magnus' radar? Either way, though, I tracked down a page that is still hosting each of the PC and Mac floppy images:http://www.synthdiy.com/show/?id=348
Oh, and if you do a search at a rather festive gear forum, you'll be able to find a large stockpile of sound disks for the TX16W.
