optimum disk performance:

3. Set the Address.
a. On the back of the 7957 A/7958A disk drive, find the address wheel
labeled "ADDRESS" in the upper left corner.
b. Set the HP-IB address:
• If this is the first disk or tape drive you are installing on the interface,
set the address wheel to 0, unless address 0 has been used elsewhere.
• If there is only one other disk or tape drive (besides this
7957 A/7958A) already connected to the interface, set the address wheel
to 2, unless address 2 has been used elsewhere.
• If there are two other disk or tape drives (besides this 7957 A/7958A)
already connected to the interface, set the address wheel to 3, unless
address 3 has been used elsewhere. If it has, choose any unused
address.
