Wow, all this SCSI talk sure sends me down memory lane.  So, Trevor, let's add another twist:  You didn't mention the distinction between active and passive terminators.  (The active ones are superior, and usually have a nice glowing diode/LED indicator when they are functioning properly.)

And I thought Master/Slave, and the jumpers involved, the position on the cable, was al that it took... oh well!

But the speeeeeeed...!!!

Kind regards,
