Hi,

I got this manual a month or so ago from the Sandisk site.  Mine is version
5.1, quite a bit newer than the link below, but version 5.2 is available.
The only difference is that the power requirements have increased
substantially.

Sorry I don't have URL.  Google for MultiMediaCard Product Manual.

Regards,

Gordon Williams
