But that's the point. While the device might incorporate a terminator, that
doesn't make it a terminated device. If the terminator is enabled then it
becomes a device plus a terminator - exactly the same as a device with a
pass-through connection and a terminator plugged into the end of the chain.
It's a fine distinction, but unless you make it clear then you will make the
mistakes apparent in your comments, confusing what a device does in terms of
line impedance etc with what a terminator does. They are different things
and they have different effects.

SCSI is complicated today. U2W cables are actively terminated. Older
standards allow terminated devices (i.e. devices with internal
termion) as well as external terminators.

As it turns out UDMA capable devices has some sort of half-assed
device terminaton, i.e. _every_ device on the bus has some pull-up
or pull-down resistirs. Quite inelegant IMO.
