Updating this old thread.
I had an Insite Flopticall in my Amiga 3000. It interfaced using the SCSI bus but using a custom mountlist entry, it would easily read MS-DOS 1.44mb disks.
It was very unreliable, but the kit I'd gotten was specific for the Amiga 3000, so it more or less fit and could be used as the second drive.
