Just about the only places where you'll find SCSI floppies are in Unix workstations from the 90s. And even then most of those used a shugart bus.. You'd probably have the best luck with old HP/Apollo workstations.
You can read 720 and 1440kB disks with those drives. Perhaps useful if you transfer little files from a PC and have no null modem cable or network connection between the two. :-)
