User Manual Sony MVC-FD7 Digital Still Camera Mavica®

The pair I got (used) did come with a charger and two
batteries, though only one of the batteries worked. Both
cameras were missing the "time keeping" batteries (CR2016, I
believe), but those were easy enough to replace.

No, that is one of the first Mavicas that Sony produced. We
have several others, such as the FD200, that were
developed later that you can use either a floppy, memory
stick and download to the computer with a USB cable. Also
as JuRo said, the USB external floppy drives can be
purchased online and don't cost a lot.
