==============

Drive Select
------------
Five jumpers are provided for logical drive number assignment. DS1,
DS2, DS3, DS4 cause the drive to be selected when the active drive
select line matches the installed jumper. Jumper G, when installed,
causes the drive to be selected constantly. The Quantum part number
for the jumper plug is 22-10036.

cable, a 220/330 ohm terminator pack must be installed at PCB
location RN3. The terminator must be removed from RN3 is the drive is
not at the end of a string of drives. The Quantum part number for the
terminator pack is 13-12302.
