I believe the answer to this is yes, but I'm not sure I  understood 
the question.

The single SCSI bus on the C600 is just like the internal/external 
bus on the S900.  So, a diagram of your C600 SCSI bus might look like 
this:


T:D===D===D===E:MB:I----D------D------D:T

Where E:MB:I is used to represent the motherboard with external (E) 
and internal (I) SCSI ports.

If you had no external devices it would appear:

T:MB:I----D------D------D:T

Where the MB automatically supplies the termination associated with it.

Without internal devices it would look like:

T:D===D===D===E:MB:T
