The problem is that my only 8" drive is attached to a dead DN420. Would a "newer" say DN3500 accept this floppy drive (temporarily) so I can get the data?

Thanks, Jim. That does sound like more work than I was willing to put in. I just wanted to test the waters and see if one of you knew what I was getting myself into before I start pulling hardware out of machines... I was planning on giving my DN420 away (hopefully for a little cash) to Bear at typewritten...Perhaps he can get the machine to work and at that point maybe he can extract the data off the floppies for me. We'll see...not a big rush on this one.
