   The SCSI2SD boards, which eventually became ZuluSCSI, used to have 
hard partitions on the SD card and used a 1:1 mapping.  Does this mean 
they're not an emulation?  So from one firmware release to the next, 
when they leveraged the beefier microcontroller to implement FAT, that 
made it no longer an implementation, but an emulation?

   Sorry, I'm not buying it.

   It's no different from, say, if a manufacturer documented the 
interface between the HDA and a drive's logic board.
