 TE (8)       |(Applies only to "W" models)
 ON           |With the jumper installed, the On-board (non-
              |removable) terminator circuits are enabled
              |(connected to the I/O lines). Default is jumper
              |installed.
              +-----------------------------------------------------
 OFF          |Terminator circuits not connected to I/O lines.
 -------------+-----------------------------------------------------
 DS  ME (7/6) |
 OFF OFF      |Spindle starts immediately after power up - Default
              |setting.
              +-----------------------------------------------------
 OFF ON       |Drive spindle does not start until Start Unit command
              |received from host. On Off Spindle Startup is delayed
              |by SCSI ID times 12 seconds after power is applied,
              |i.e., drive 0 spindle starts immediately when DC
              |power connected, drive 1 starts after 12 second
              |delay, drive 2 starts after 24 second delay, etc.
              +-----------------------------------------------------
  ON ON       |Drive spindle starts when Start Unit command received
              |from host. Delayed start feature is overridden and
              |does not apply when ME jumper is installed.
 -------------+-----------------------------------------------------
  WP (5)      |
  ON          |Entire drive is write protected. Off Drive is not
              |write protected. Default is no WP jumper installed.
 -------------+-----------------------------------------------------
  PE (4)      |
  ON          |Parity checking and parity error reporting by the
              |drive is enabled. Default is PE jumper installed.
              +-----------------------------------------------------
  OFF         |Drive checks parity, but does not report result of
              |parity checking to host.

 J1-Auxiliary |
 Jumper       | Jumper Function Description ("W" models only)
 Installation | Drive ID on SCSI Bus (J1-auxiliary or J6 may be used,
 A3,A2,A1,A0  | as the ID circuits are wired in parallel).
              | The drive ID is binary coded positionwise i.e. jumper
              | in position A 3 is drive ID 8, A 2 is drive ID 4,
              | position A 1 is ID 2, position A 0 is ID 1 and no
              | jumpers is ID 0. Default is ID = 0. Both J1- auxiliary
              | and J6 should not be used at the same time, because at
              | some future time when the ID is changed the user could
              | fail to configure both J1-auxiliary and J6 the same.
              | "WC/DC" Models, do not have J1-auxiliary.
 -------------+------------------------------------------------------
 -------------+------------------------------------------------------
 J6 Jumper    |
 Installation | Jumper Function Description ("W" and "WD" models only)
 A3,A2,A1,A0  | Drive ID on SCSI bus. Either J6 or J1-Auxiliary
              | (optional) may be used to select drive ID. Both
              | should not be used at the same time, because at some
              | future time when the ID is changed the user could fail
              | to configure both the same. Default is ID = 0.
 -------------+------------------------------------------------------
 -------------+------------------------------------------------------
 LED          | Time shared J6 pin 8 used to connect a
              | cable for a remote drive activity LED indicator. Pin 8
              | (bottom), the cathode connection, connects in the
              | drive to GRD through the emitter-collector junction
              | of a transistor switch that controls the LED on/off
              | condition. Pin 11, the anode connection, connects in
              | the drive to the +5 V supply through a pull-up
              | resistor.
 -------------+------------------------------------------------------

 NOTE
 The PCB on "WC" models does not have connector J1-Auxiliary. It
 has a single 80 pin combined SCSI I/O and DC power connector instead
 of the 68 pin SCSI I/O and 4 pin DC power connectors. Includes among
 the 80 pins are the SCSI ID, Motor Start and Delayed Motor Start
 select functions, and the remote drive activity LED signal. Do not
 use J6 for these functions if the host uses the ones included in the
 80 pin J1 connector.

 NOTE
 Jumper header J6 can be used in one of five possible ways:

 - Do not use J6 at all, but instead use the same functions conveyed
   on lines in the 80 pin I/O J1 connector ("WC" models), or for
   "W" and "WD" models, use J1-Auxiliary.

 - Use jumpers on J6 only to establish drive ID on the SCSI bus. Do
   not use both J6 and J1 or J1-Auxiliary signals to establish the
   drive ID. The drive activity LED signal in connector J1 or J1-
   Auxiliary may be used to convey that signal to/from the host.

 - Install a connector/cable on J6 for remote drive ID switching. Do
   not use both J6 and J1 signals to establish the drive ID. The drive
   activity LED signal in the 80 pin J1 I/O connector or J1-Auxiliary
   can be used in this situation.

 - Install a connector/cable on J6 for remote Drive Activity LED.
   Use the 80 pin I/O connector J1 for the drive ID signals ("WC"
   models) or J1-Auxiliary ("W" and "WD" models).

 - Install a connector/cable on J6 for all (remote ID switching and
   remote drive activity LED). Do not use both J6 and J1 or J1-
   Auxiliary to establish drive ID.
