Wide n' Skinny SCSI

It doesnt.

Address lines greater than 7 are on 16-bit cable data lines 8 thru 15 which an
8-bit device never sees.

Hi,

	The other question I have related to this is what about SCSI ID 
addressing? How does an 8-bit device sort out wide addresses?

Is there any document or TIB or words of wisdom regarding the mix of Wide 
and 8-bit devices on the same SCSI bus?  My limited experience has been 
successful with hybrid cabling schemes inserting the 8-bit devices in the 
middle of the bus and terminating both ends with wide terminators.  Are 
there any more subtle gotcha's?
