Well it never really was alive to begin with, but the website (www.tapwave.com) has now announced that it has dropped support:
We are sorry to inform you that the Zodiac business was discontinued and service and support are no longer available as of July 25th 2005.
Resources that may still be helpful to you can be found at http://www.tapwave.com/resources and http://www.tapwave.com/support. This includes links to websites where you can find a variety of useful tips and information as well as purchase e-books, Audible books and magazines, Palm OS applications, Zodiac skins, and third party Tapwave Certified games.
Additional products, accessories, and game cards may still be available from COMPUSA, Fry's, and J&R while supplies last.
We thank you for your past interest and support and apologize for any inconvenience that this may have caused. If you have an outstanding claim with the company, Ueker and Associates will be contacting you shortly.
Sincerely,
The Tapwave Team
