You are aware of the Catweasel Flipper, are you? That cute little feline/weasel/whale should make it possible to read bogstandard Amiga floppies on the A1.
Yeah okay, doesn't answer your question but still, your floppies will not be completely unusable (untill they will disintegrate of age ofcourse, and this it probably WHY you want to ADF them) =).
