Not to arguing, but this is from the SCSI FAQ:
In an extensive survey of cables available in the US and Europe, we
found that more than half of the cables available have single-ended
impedances in the 65 to 80 Ohm range -- below the 90 to 132 Ohms
specified in the SCSI-2 spec. It seems that some (not all) cable
vendors do not understand the specification, describing their cables
as SCSI-2 compliant when they are not. A common misconception is that
SCSI-2 means a high-density connector. In fact, there are several
connector options.
Enjoy!
