I don't think the one that he's talking about is SCSI, it plugs directly
into the floppy port on a Mac 128k or Mac 512K. ISTR, using one on a newer
Mac Plus instead of a SCSI drive as I needed something of that formfactor
and that was all I could get my hands on at the time.
Based on how it's used, I'm guessing you're right about it being a MFM
drive, but I suspect it's some wierd sort of bridge in it.
