Dick,
The pin sets labeled A0, A1 & A2 would be the ones needed to set the
SCSI ID #. If the drive was bought new, the SCSI ID should be set to
0 already (this is the factory default setting). This means that all
three sets of pins are set to OFF (ie none of the pins are shorted by
the jumper[s]). Please note that pins are OFF if the jumpers are NOT
connected. With that the following table should give you the SCSI ID
numbers (just from one of my Quantums, as the other is an external):
A0 A1 A2
0 OFF OFF OFF
1 ON OFF OFF
2 OFF ON OFF
3 ON ON OFF
4 OFF OFF ON
5 ON OFF ON
6 OFF ON ON
7 ON ON ON
Do not use SCSI ID 7 as this is usually used by the controller itself
(think of the controller as another SCSI device on your SCSI chain). The
extra set of jumpers are probably for the LED display (you do not need to
worry about hooking this up as it has nothing to do with the HD's
operation, it is more for the operator to show that the HD is being
accessed). Hope this helps.
