The card itself works with a SCSI drive. However, the Sider firmware
does not. I've tried this some time ago. The formatter program uses one
of the user-defined SCSI (SASI) commands to read status info from the
MFM-SASI bridge. Regular HDs do not support this. 

And the Sider firmware uses 256 byte sectors. Today most HDs have a
fixed sector size of 512 bytes (SCSI allows to specify the block size
during formatting, but today's drives ignore it).

If you write your own GS/OS driver, you'll have a low-cost SCSI
interface.
