Yup, Alexh is correct.
No SCSI card for the expansion slot needs a driver, you do however need the correct software to partiton the drive, which is suitable for OS1.3, is that what you need?
Oh and if yours is the one posted on Ebay (and pics of it in another a.org topic) then it looks like its missing the 74LS244 IC from near the edge connector. (Unless the chip up by the switch is a LS244)
