IIRC, the SII is a rather primitive chip, so it probably won't make much
sense to start with a driver for a highly complicated SCSI controller.

I think the 5380 driver would make a good template. I hacked around with
the 5380 on my Mac Plus many years ago and remember it was rather an 
enhanced parallel port ;-) - i.e. you have to implement most of the
SCSI protocol in the driver as the chip doesn't handle it for you. The 
more recent SCSI controller IC's (e.g. the 53C810) have their own 
microcontroller to control the SCSI sequencing etc.
