I was going to suggest this.  The Focus drive requires no driver.  A
SCSI hard drive requires no driver either.  If the drive interface is
designed in the correct way, Prodos will automatically recognize it and
be able to read from the disk.  I found an article on Ground that went
into some detail on this.  As Jeff B. hinted, if you make your
interface appear to the Apple II as a standard block storage device (as
most mass storage interfaces for the Apple II do) you don't need to
write a driver.  This may require extra circuitry and I don't know if
the tradeoff is worth it.  Code a driver for the card, or modify the
interface to interact with the Apple II like a standard block storage
device.
