There is no rule stating that Apple isn't allowed to change a part number
when the part changes.  In fact, the "Rev. C" or "2.0" Apple II SCSI Card
ROM has part number 341-0437-A.

A common misconception:  Advanced Disk Utilities (ADU) has this intricate
knowledge of the system that other programs can't have.  Not true; ADU only
works with devices that GS/OS has found, and issues device-specific DControl
and DStatus calls to those devices owned by the SCSI Manager.  Any program
can do what ADU does.

GS/OS (and therefore ADU) won't recognize anything connected to a SCSI card
unless the SCSI Manager is present.  Boot your original 5.0.2 disks (or 5.0,
if you don't have 5.0.2 yet), run the Installer and Install What Needs To Be
Installed on your hard drive (probably "Latest System Files" and "SCSI Hard
Disk").  At least install "SCSI Hard Disk" onto *any* disk you want to boot
from if you want to use the hard drive.
