PREFACE
This manual explains the MAW3073/MAW3147/MAW3300/MAX3036/MAX3073/MAX3147 NP/NC
series 3-1/2" intelligent disk drives each having the built-in SCSI controller.
This manual details the specifications and functions of the Small Computer System Interface (SCSI) to
connect the above listed disk drives to the user system. Also, the manual details various SCSI command
specifications and the command processing functions, and provides the information required to creation of
host system software. This manual is intended to be used by the users who have the basic knowledge of
computer system operations.
The following lists the manual configuration and the contents of each chapter. The caution labels and
markings are also explained.
