Hi,
I recently had a discussion with Casio regarding the Z-PDA and the AST
Gridpad. They confirmed that they manufactured all of them and they are
identical EXCEPT THE SILK SCREEN ON THE CASE!
Let's put this one to rest - THEY ARE IDENTICAL - All accessories are
compatible and the software is identical.
Also, the AST's on sale have been sitting in a warehouse since their
manufacture date of December, 1993!
