The four pin J01 connector is for Termination Power. You should set that to External Termination Power Source (pin 2 to pin 4) unless you're using a poor cable which does not provide the Termination Power line, in which case you should use "Internal Termination Power Source" (pin 2 to pin 1). The Termination Jumper is on J4A over where the SCSI ID pins are. There's a block of six pairs of pins on the left, then a blank and then a block of three pairs of pins. The right most of those three pairs should be jumpered for termination. However, if you are using an external SCSI case, why not disable termination on the drive and use an external termination on the SCSI case's second SCSI connector? This is much easier to deal with and keep track of. SCSI Termination Power is not the same thing as Termination, and while the Termination Power settings sometimes don't matter much, I've found that Seagate drives can be very finicky if there is more than one source of term pwr on the bus. Generally, the SCSI host supplies Termination Power. >Today I tried it in conjunction with another SCSI drive, which was detected. >I can't figure it out.

This is found in the other Mac II family machines. That drive works fine on my IIci. It's a washing machine, but it works fine and is good as an archive volume.
