In my case, I used a Mac LC as the 800k floppy <-> SCSI interface, because I already had one in the collection. It's more bulky than the FluxEngine adaptor though! The full route from Internet to Mac SE 800k floppies was: WiFi -> MacBook Pro 2014 -> USB-PATA hard drive -> PowerBook G3 Wallstreet (screwdrivers) -> SCSI HDI-30 to DB-25 adaptor -> SCSI hard drive -> Mac LC -> 800k floppy -> Mac SE. The SCSI drive had to be formatted Mac OS Standard (HFS) not Mac OS Extended (HFS+) if I remember right. Copying data each way took half an hour, so the FluxEngine would be a lot smaller and quicker.
