NOTE
For attachment to a Macintosh, place jumpers on pins 29 & 30 to
Disable Unit Attention and pins 11 & 12 for Auto Start.
Auto Start (& Delay) Pins
-------------------------
The Auto Start and Auto Start Delay pins control when and how the
drive can spin up and come ready. When configured for Auto-Startup,
the motor spins up after power is applied without the need of a SCSI
Start Unit command. For no Auto-Start, a SCSI Start Unit command is
required to make the drive spin and be ready for media access
operations. When in Auto-Start mode, the drive will delay it's start
time by a period of time multiplied by it's own SCSI address.
Write Protect Pins
------------------
If the Write Protect pin is jumpered to ground the drive will
prohibit SCSI commands that alter the customer data area portion of
the media from being performed. The state of this pin is monitored on
a per command basis.
Disable Sync. Negotiation Pins
-------------------------------
If a Disable Target Initiated Synchronous Negotiation pin is grounded
then an Initiator is required to start a negotiation handshake if
Synchronous and/or Wide (Double Byte) SCSI transfers are desired.
Disable SCSI Parity Pins
------------------------
Grounding this pin will disable SCSI Parity checking.
Disable Unit Attention Pins
---------------------------
Grounding this pin will disable the drive from building Unit
Attention Sense information for commands immediately following a
Power On Reset (POR) or SCSI Bus Reset. Any pending Unit Attention
conditions will also be cleared at POR or SCSI Reset times.

The drive will operate in all axis (6 directions).
Mount the drive securely, using the appropriate brackets or rails, in
any axis, using four 6-32 UNC metric screws in the bottom or side
mounting holes.
The maximum screw insertion depth for mounting is 3.8 mm (.15 in).
