AFAIK, yes - that's correct. The 50-pin (narrow SE SCSI) should be terminated
on the external 50-pin high-density connecter. The 50-in ribbon cable has a
terminator at the "internal" end. It's all one bus.

It's intended for 2 HDs and a CD-ROM or SCSI FLoppy.

I think so.

Yes. But it works w/o termination too since the cable is vry short
if nothing external is connected.
