orig. Apple 5.25" disks as I know work only with Macintosh SE and Macintosh II (According to Apple, the drive and controller cards are not compatible with Macs with FDHD ROMs.) And with Apple File Exchange application. I got Mac SE with this 5.25" floppy drive and the disk drive is not operating with mac os, but only trough as I said before Apple File Exchange app.

So I agree with Charlie man ...
