why don't you just simplify your life and get a Buddha card and IDE drive? far simpler and performance isn't that much less, if you got a really new IDE drive, probably all but equal on an Amiga, actually.
I spent many an hour dealing with SCSI termination issues in my old A3000D before I got rid of it - in my current A2000 I have a DKB wildfire with one drive, and a Buddha with a second. The also nice thing about the Buddha is then you can put in IDE CD-ROM drives, etc., FAR cheaper than SCSI CD drives.
And since it's an Individual Computers product, the Buddha is completely, utterly reliable, and not 15 years old, either.
good luck!
