I have not seen much in the way of parallel SCSI target hardware
anywhere, other than efforts mentioned earlier here to use various chips
for target emulation on PC's.
I would think that some effort with an FPGA could produce a fairly nice
10mhz scsi target, and if a PIC was attached to it with USB support, one
could write a program that could communicate with the PIC and host
emulated storage on the USB host.
I don't think the concept of USB storage does much for you, unless you
were to also include the storage on the USB /SCSI hardware device and
make the SCSI access the storage which the SCSI target would also be
accessing.
That would be interesting, but not so useful either as that storage
would still not make sense to the host, unless you were using fairly
modern disk mappings and they could be read via current USB drivers from
a host.
If you put say an SDram on the small dongle with the USB device and SCSI
target hardware, it would run fairly well though.

Anyone know of such a
device? There are plenty of devices to allow you to access a SCSI disk via USB but I
haven't found one that works the other way....
