Sony made those "floppy" adaptors for the original Mavica cameras. Not good memories of them. The product was nice enough, the drivers though were fantastically buggy, craptastic and incredibly slow. To read 1M took longer than what it took to write and verify to a real diskette. As a lus the software did come on a pair of diskettes though, no CDROMS for the first time. Of course only supported Sony MS and only the ones up to 8M. They might have improved later, but USB was more common by then, and there were drivers that did then like Sony cameras.
Still have the camera, even with the batteries so old that you get to take 3 photos between charges.
