[comp.sys.amiga.programmer] Using the Amiga as a target SCSI emulator

steve@cpoint.clearpoint.com (Stephen Steir) (02/11/91)

I'd like to use the Amiga as a target SCSI device in order to test some
SCSI disk controllers we've built here.  I need it to do basic emulation
like handling read and write requests but I also need to inject parity errors
and build my own packets.

	You'll have to control the hardware directly to have a chance at
it.  I advise against it, but if you want to do it you'll need the WD 33C93A
docs, and I you can ask me for information on how to get to the WD registers
through the Super-DMAC chip.

	The current driver has no target-mode support.  Perhaps one of the
3rd-party controllers does.
