Hawk 2LP family "WC" and "DC" model 80 pin SCSI
I/O drives
On Hawk 2LP family "WC" and "DC" model drives there
is no J1-auxiliary connector. J6 can be used to set drive
ID, but the host probably does it over the 80 pin
interface. J6 can also be used to drive the external drive
activity LED indicator signal. The alternate use of J6 is
described in the notes following Figure 3c.
