Gee, this is really interesting. In the sense of the Chinese curse,
of course. Does this mean that "Internal, jumpered termination
doesn't work on IBM drives" even if they are the only drive on a given
SCSI branch? What about external termination? If you run a computer
store, you presumably have tried this -- do they have terminators that
plug onto the ends of those nifty internal ribbon cables?
