The most difficult part of that project was finding the actual programming
specs for the card. They are out there; search long enough and you will
probably find them...

The one doc I recall as being the most useful was R2_MMC1.pdf and was
originated by SanDisk.  I seem to remember lots of googling and whatnot to
find the 'secret' cache wherein it resides.  But just for you, it will be
available for about a week or so here:

        http://home.thegrid.net/~i272533/anything/teknoid/

It's about 1.7 MB and I'm not sure how full my disk quota is so I'll delete
it in a week or so. Get it while it's hot!

Good luck!
Tom
