SCSI to IDE

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.
