Not sure if this was covered, but when I was searching for a 68->50 pin SCSI adapter, there were two types. One provided an option for termination and the other didn't. I think 68pin SCSI handles termination differently than the 50pin, thus no option/jumper on the drive. It'd be on the adapter.
Oh also the SCSI ID options were on the adapter, too, not the drive. It was an IBM 9GB 68pin SCSI drive I'm referring to.
