I have one of these in very good condition. I looked at the floppy drive and from what I have found it's a standard 1.44MB high density drive like any other. I purchased a GOTEK USB floppy drive emulator unit which I have used successfully on other items but I can't seem to get it to work on the SD-35. Anyone familiar with getting this arrangement to work or know of another solution? I really don't want to keep the original floppy drive in the SD-35.
