SD cards are attractive in many ways. For one thing,
they can be accessed
via an SPI interface which saves some I/O pins on that end. Since I really
know nothing about SCSI, I don't know if that is a good approach for a
SCSI/SD adapter or not. I wonder if there are any real time requirements
in a SCSI interface that would be impacted by talking to the SD card in a
bit serial fashion.
HDSD cards are speedy enough to be used as SCSI drives. I think how
command queueing would work, but being a "for fun" project, I believe things
can be implemented, one by one.
I'm studying whatever I can find about SCSI. Seems I'll dive deep on
this project as soon as I can get my lab back. I want to have my name
remembered by the comunity he he he :o)
