I seem to remember something about this... Don't you have to turn
on everything in the SCSI chain for it to work? Or is that only
to use the device at the end of the chain?? Or am I just
imagining things??? :-)

???!!! What?? That doesn't sound right! *Both* are terminated?
Actually, come to think of it, it depends on where the SCSI chain
begins and ends. Does it start at the Mac, or does it start at
the first device? If it starts at the Mac, then you should get
the termination removed from the first drive in the chain.
