Getting file system access to my duos Hard drive

I have a duo 210 that won't boot, and I seem to have lost the floppy drive for it. I want to get access to it so I can fix my finder and system files (played around with them in resedit and swapped them). I need to be able to move the backups of the original files back into the system folder and delete the ones I screwed up. Are there any adapters (scsi to usb etc) I can buy to hook the drive up to my new computer to access them, or do I need to get a floppy drive and system 7.1 install disks?

Back when I still had the floppy drive I booted up with the duo disk tools floppy (now corrupted and unusable) and it wouldn't let me move the files, only look at them.
