Yes, indeed.  Implementing a SCSI target would certainly be easier, and
probably adequate for most systems that you'd want to use.  That would
solve a set of real-world problems; the reason I originally started
working on a SCSI/ATA bridge was that I was fed up with having to find
old SCSI hard disks to use with my MDFS.

I can't think offhand of any particular functional reason why one would
want to emulate a disk at the ST-506 interface level and, though it's
interesting to think about how it might be done, I'm certainly not about
to rush off and do that.  In ST-506 terms I am actually more interested
in finding a way to read the data (if any is still recoverable) from the
old HDFS drive that is still sitting under my desk.  I had a brief poke
at that late last year, using an MFM controller card in a Linux host,
but didn't get anywhere at the time.
