My first digital camera used Smartmedia. I had a 32MB card, if memory serves. I could pull pictures off via a serial interface, which was slow and required a proprietary app, or via a FlashPath[0] adapter. Sadly, FlashPath adapters require a driver and aren't actually emulating a floppy diskette. Putting the reader into a floppy diskette shell and using the disk interface to transfer data is still a pretty cool hack, though.

Sony made a Memory Stick adapter like this, too. I imagined that one day someone could back up their computer to a Memory Stick.

(Alas, still a dream, as the Transcend JetDrive Lites for MacBook Pros are as unreliable as they are slow. Never put data on a JetDrive Lite that you want to last more than a couple of days because you never know when it might just suddenly stop responding for no reason.)
