Re: Panasonic Comments to Letter Ballot X3T10/95-014r0

Dear X3T10:

In resolving the NO vote from Panasonic Technologies, Inc. regarding Letter
Ballot X3T10/95-014r0, please consider the following comments as reasons for
the NO vote. Panasonic Technologies, Inc., is opposed to the formation of a
new Technical Committee under X3 to be assigned the ATA projects 791-M,
948-D, 1120-D and 2008-D) for two primary reasons.

1)   Separating the work of ATA and SCSI (both presently assigned to X3T10)
will not be conducive
     to industry convergence. Both ATA and SCSI are considered Low-level
interface for computer
     peripheral devices and are therefore appropriately assigned to X3T10
given its charter
     of Low-level interfaces.
     a)   Recently, there has been a trend to bring some commonality between
ATA and SCSI. This
          is very apparent in the more advanced ATA projects such as ATA-2,
ATA-3, and ATAPI
          which all "borrow" significantly from SCSI. This commonality is
very important at many
          areas in the industry especially in the area of operating systems
and device drivers.
          ATA efforts have adopted the CDB structure of SCSI making it
easier for developers and
          system integrators to make implementations which share development
investments. This
          is a benefit to both manufacturers and users.

     b)   X3T10 has formed a Systems Issues study group which has been
investing significant
          effort toward addressing ATA and SCSI convergence issues such as
the SCSI command
          structure in ATAPI and is now investigating command overlap for
ATA. If ATA were moved
          to a separate TC we would loose a important opportunity to have
some level(s) of
          compatibility between SCSI and ATA and instead we would be
encouraging the inefficient
          practice of duplication of effort.

2)   Segregating ATA to a separate TC will significantly hinder the
opportunity for Panasonic
     Technologies, Inc. and other companies to participate in the process of
developing these
     a)   At the May meeting of X3T10 in Harrisburg, PA, it was very
apparent that a primary
          reason to form a new TC for ATA was to limit the meeting locations
to the California
          area. This places member companies not located in that geographic
area at a significant
          disadvantage because of the increased travel cost and time
investment necessary to

     b)   It was also apparent at the Harrisburg meeting of X3T10 that there
was an intent to
          increase the frequency pf the ATA meetings. This too places member
companies not
          located in that geographic area at a significant disadvantage.

     c)   Limiting meeting location and having meetings more frequently that
six times per year
          appears to be direct violations of the X3/SD-2, Organization,
Rules and Procedures of
          X3, sections 4.3.2 and 4.3.1 respectively.
