I asked this question a few months ago.  I'm starting a software project to
write a driver for our user group's SCSI controller.  It will actually be
two drivers:  

    "scsi.device" to talk to arbitrary SCSI controllers on the bus

and

    "scsidisk.device" which will emulate (of course) a trackdisk.device 
interface and use scsi.device to talk the the disk controllers.

Existing products that I know about (e.g. C Ltd) have one monolithic driver
which has no (documented) hooks to issued commands to device on the SCSI bus.

I hope that C-A has such an interface, and is willing to release the interface
specifications so that other can emulate it.  Is there any tech documentation
on the A2000 SCSI/ST-506 controller that describes the software interface?

Do you really expect to back up your 30M disk to floppies?  Be real.  I wish
I had a QIC02 SCSI controller and drive.  But if I did, I guess I'd be frantic
trying to figure out a way to use it.  Then again, I wish my C Ltd drive would
come back from C Ltd..  *Sigh*
