How about using a PC to emulate a SCSI drive?
Found an interesting blurb at

Haven't pursued it any further but it might be simpler then building your own.

Most SCSI drives (primarily CD-ROMs) I worked on had fairly simple
interface logic, and the bulk of the heavy lifting was done by the
microcontroller. I've been trying to track down a datasheet for one of the
old Cirrus Logic SCSI CDROM chips, but thus far have been unable to. The
chips I worked on had a moderate amount of automation (possibly even
scatter-gather support), but in essence were just fancy DMA controllers
that could handshake with a SCSI host.
