I'm pretty sure the 53C9[0|4|6] chips can be run as both target and

some state machines for going through the more standard SCSI commands
and a DMA interface.
It's been a few months since I was poking through the datasheets,
though, so again, I could be imagining things.

Reprogramm a NCR / Symbios 53Csomething to act as a SCSI
target, emulating a SCSI disk that is backed by an image file on the
host machine.
I've seen it said that only some SCSI interfaces are capable of target
mode. Anyone know how true that actually is? As much as I like SCSI,
I'm not that familiar with typical implementations and how much they
put in silicon versus firmware....
