not strictly a processor specific question, sorry, ( and if anyone knows 
of a better place to ask it, please tell )

I'm trying to build some s/w to talk to a MicroSD ( previously known as 
TransFlash ) card in SPI mode.

There don't seem to be any published data sheets on the SanDisk web 
site, they just say "conforms to the specification"

But you can't get the specification without paying $oodles to join the 
interest group.

This is nonsense - I don't have this problem with other components.

My immediate need is to know what SPI clock speed it will talk to me at.

But I suppose if I have that I'll immediately need the s/w info for how 
to interact with it. I think most of that is in the filleted document 
they so graciously allow you to download.

I know a number of people around here have written stuff to talk to 
SPI-SD cards - is any of it GPL or anything so I can go get it to see 
how it's done?
