                              Results of Meeting

1.    Opening Remarks

John Lohmeyer, the X3T10 Chair, called the meeting to order at 1:00 p.m.,
Thursday September 15, 1994.  He thanked Bill Galloway of Compaq Computer for
arranging and hosting the meeting.

John said that X3 Subgroup Membership forms and the X3T10 Mailing
Subscription form were available on the document table.  He said that people
should use the X3 forms to insure the X3 Secretariat has the latest
membership information.  These forms should be mailed directly to the X3
Secretariat.

As is customary, the people attending introduced themselves and a copy of the
attendance list was circulated.  Copies of the draft agenda and general
information on X3T10 were made available to those attending.

2.    Approval of Agenda

The draft agenda was approved with the following changes:

Deletion of CAM forwarding for second public review.  Addition of the
following new business items; ECMA [Cummings], Reserve & Release [Weber],
MEDIA FORMAT command [Cummings], other working group recommendations
[Lohmeyer].


3.    Attendance and Membership

The membership requirements were reviewed.  X3 rules permit one vote per
organization.  An individual from a new organization must attend two out of
three consecutive plenary meetings.  He/she may apply for voting membership
the second meeting via a letter to the Chair of X3T10.  The individual may
vote at the second plenary meeting.  Working group meetings do not count
toward attendance requirements.

Organizations must also pay the X3 Service Fee ($300) to maintain membership. 
This year, the International Program fee ($300) will be billed separately
directly from ANSI.

The Chair said he had sent letters to 29 people from 15 organizations
informing them that their membership was in jeopardy due to non-attendance
(see 94-009r2) and that their membership would be terminated if they did not
attend this meeting.  Rancho Technology requested that their membership be
converted to observer status.  All organizations were represented except: 
Distributed Processing Tech., Pacific Electro Data Inc., Ricoh Corporation,
and U.S. Design.  Principal members from these organizations were changed to
observers and the alternates were terminated.

The following organizations joined X3T10 at the meeting: Burr-Brown Corp. and
Syquest Technology, Inc.

The X3T10 membership is now at 58 organizations down from 61 organizations
last time.  Enclosure (1) is the list of the people present at the meeting
and enclosure (2) is the current X3T10 membership list.

4.    Approval of Minutes - July Meeting Bedford, NH (X3T10/94-150r1)

The minutes were approved as written.

5.    Document Distribution

Members who have any problems with their mailing subscription should deal
directly with Katrina Gray or Dan Arnold at (202) 626-5741.

Larry Lamers requested that all documents for the next mailing must be sent
so as to be received by noon on Thursday, September 29, 1994.  Documents
received after this date will go into a subsequent mailing.

Larry Lamers reminded the committee of the requirements for document
submission to be included in the committee mailing.  Since X3T10 meets its
document archiving requirements by including the X3 Secretariat on the
mailing list, documents included in the mailing must be suitable for
microfilming.  This means that high-quality, single-sided originals with
adequate margins and proper identification must be submitted.  Document
X3T9.2/92-84 R1 contains the list of requirements for submissions.

As usual, minutes are also available on the SCSI BBS (719-574-0424) and will
be distributed to the ATA and SCSI Reflectors.  To be added to the ATA
Reflector, send an email to majordomo at dt.wdc.com with the line 'subscribe ata
your-email-address' in the message body.  To subscribe to the SCSI Reflector,
send an electronic message to: scsi-request at WichitaKS.NCR.COM.

The current document register is enclosure (3).

6.    Call for Patents

This is a regular agenda item to identify any potential patent issues with
developing standards.

A document is available from ANSI, "Procedures for the Development and
Coordination of American National Standards", at no charge.  Annex I contains
the ANSI patent policy.

7.    Review of Old Action Items

8.    Subgroup and/or Project Status Reports

8.1   Project Status Summary [Lohmeyer]

John Lohmeyer said that the current X3T10 project status summary was included
on the backs of the meeting agendas.  John noted that the Fast-20 project was
approved.

John reported on two correspondences that he has received that might affect
X3 and/or X3T10.  The first concerns IEEE project 1149.5/D0.9.9 called
standard module test and maintenance (MTM).  The second correspondence came
|from OMC and concerned two futurebus projects.  There was no interest in
forming formal liaisons.

8.2   X3T10.1 Task Group Report

John Scheible reported that X3T10.1 is forwarding a project proposal for a
technical report to X3T10.  The technical report is a mapping of SCSI-2
commands to SSA.  Ed Gardner reported that the motion to forward was approved
19:0:0:38.  Larry Lamers took an action item to process the X3T10.1 project
proposal via an X3T10 letter ballot.

8.3   SCSI-2 Status {Project 375-M} [Lamers]

Published!  At last!  Call ANSI at 212-642-4900 to order your copy.  The
price is $125 ($100 for ANSI member companies).

8.4   SCSI Common Access Method (CAM) {Project 792-D} [Dallas]

Bill Dallas noted that additional comments had been received concerning the
host target mode clauses.  Bill described his plans to prepare a revised
draft of CAM in time for the next mailing.  Bill said that he will be asking
for a forwarding to second public review at the November plenary meeting.

8.5   AT Attachment (ATA) Status {Project 791-D} [Lamers]

Larry Lamers moved that we approve payment of the $350 invoice for editing
the ANSI editor's comments to the ATA document.  Bob Masterson seconded the
motion.  The motion was passed 41:0:0:17.

8.6   ATA Extensions (ATA-2) Status {Project 948-D} [Finch]

Since the last plenary meeting, the ATA Working Group has met twice.  On
August 31 and September 1, the working group performed a technical review on
ATA-2, and completed its review of the document through Section 6.  This
represents the first 37 pages of a total of 105 pages, so there is much work
yet to be done.

A number of rather significant changes were made in the sections reviewed,
and register definitions in particular.  Steve Finch recommended that anyone
who is interested in the ATA interface to take the time to review at least
through section 6.

This morning, September 15, the ATA Working Group met and addressed the
following issues: 

   Submittal of ATA-1 for ISO standardization:  the working group did not see
   a need for the submission of ATA for ISO processing at this time.

   Resolution of comments on the ATA-3 and ATAPI project proposals:  the
   working group made no changes to the project proposals based upon the
   comments received.  The working group did create proposed responses to
   each of the no votes.

   A proposal for multi-threading on ATA/ATAPI was presented by Western
   Digital.  A copy will be in the next mailing.

The ATA-2 document is currently at revision 2g (X3T10/948Dr2g).  Hard copies
were available at this morning's meeting.  Some copies were left over and
were available at the X3T10 meeting.  A copy will be in the next mailing.

The next ATA Working Group Meeting is scheduled for September 27, 9:30 a.m.
to 5:00 p.m. and September 28, 9:00 a.m. to 4:00 p.m.  The meeting will be
hosted by Quantum at the Crown Sterling Suites in Milpitas, CA.

Other scheduled ATA Working Group Meetings:  Thursday and Friday, October 20,
21 in Milpitas; Thursday, November 10, 9:00 a.m. - 12:00 n.

The September and October meetings will concentrate on completing the ATA-2
document review.  The November meeting will discuss ATA-3 and ATAPI related
issues.

8.7   SCSI-3 Architecture Model (SAM) Status {Project 994-D} [Monia]

Charles Monia reported that the working group reviewed the proposed responses
to comments from the SAM letter ballot.  The document is 94-173r1.  The
working group discussed two other proposals that have been brought to the
Plenary for action today.

8.8   SCSI-3 Parallel Interface (SPI) Status {Project 855-D} [Lamers]

Larry Lamers reported that several minor editorial changes are required to
SPI.  Larry moved that X3T10 authorize spending up to $2,200 on editor
services for SCSI-3 documents in Frame.  Charles Monia seconded the motion. 
The motion passed 41:0:0:17.

8.9   SCSI-3 Interlocked Protocol (SIP) Status {Project 856-D} [Penman]

Bob Masterson moved for approval of $300 to pay the invoice for editorial
work on SIP.  Gary Stephens seconded the motion.  The motion passed
43:0:0:15.

8.10  SCSI-3 Generic Packetized Protocol (GPP) Status {Project 991-D}
      [Stephens]

Gary Stephens announced that the TIB form of GPP was in the mailing.  John
reported that the changed project proposal has been sent to X3.  Roger
Cummings reported that OMC probably is considering the matter at their
meeting this week.

Gary Stephens moved that revision 8 of GPP be accepted by X3T10 as the
current working draft.  Charles Monia seconded the motion.  Gene Milligan
asked whether prior letter ballot comments have been addressed.  Larry Lamers
reported that a comments resolution document was registered in February.  The
motion passed unanimously.

Gene Milligan asked John Lohmeyer to process a letter ballot for GPP as soon
as the project is approved.  John did not accept the action item as the X3
letter ballot is likely to close just prior to the November X3T10 meeting.

8.11  SCSI-3 Serial Bus Protocol (SBP) Status {Project 992-D} [Marazas]

Scott Smyers reported that all public review comments have been incorporated. 
Revision 13 is in the mailing.  Scott and Gerry believe that revision 13 is
ready to send to first public review.

8.12  SCSI-3 Fiber Channel Protocol (FCP) Status {Project 993-D} [Snively]

Bob Snively reported that issues have been raised that intend to simplify
target handling of recovery abort operations.  The changes are substantial
and technical in nature.  Bob noted a proposal on the agenda from Gene
Milligan that will keep the current FCP document and start an FCP-2 project,
in which the new technical material will appear.  Gene's specific proposal
is wording of a note to be placed in the current FCP document (see item 9.2).

8.13  SCSI-3 Primary Commands (SPC) Status {Project 995-D} [Weber]

Ralph noted that the Reserve/Release commands, PORT STATUS command, log page
8, and download microcode changes need to be included in the SPC.  Ralph said
that revision 3 will incorporate these changes and will be distributed in the
next mailing.  Baring unforeseen complications, Ralph hoped that revision 3
will be ready for a forwarding letter ballot for first public review.

Ralph described changes in the attached medium loader usage requested by
Erich Oetting.  The changes make the attached loader model useful for
stackers, an important variant of attached medium loaders.  As a result of
the changes, the complexity of READ ELEMENT STATUS response data increased
beyond the level that Ralph found acceptable.  So, Ralph and Erich will work
to move most of the medium changer model and command specifics out of the SPC
and into the SMC.

Ralph Weber moved that SPC revision 2 be accepted as the X3T10 working draft
for project 995-D.  Paul Johansson seconded the motion.  The motion passed
unanimously.

8.14  SCSI-3 Block Commands (SBC) Status {Project 996-D} [Tewell]

Rick Tewell reported that he plans on distributing revision 0 the SBC in the
next mailing.

8.15  SCSI-3 Stream Commands (SSC) Status {Project 997-D} [Lappin]

Ted reported that there will be a study group for stream commands at the
November meetings.  A revision of the SSC was in the last mailing.

Ted moved that revision 1 of the SSC be accepted as a committee working draft
for project 997-D.  Erich Oetting seconded the motion.  The motion was passed
unanimously.

8.16  SCSI-3 Graphics Commands (SGC) Status {Project 998-D} [open]

There is no editor for this project, however Rick Tewell has found a hot
lead.

8.17  SCSI-3 Medium Changer Commands (SMC) Status {Project 999-D} [Oetting]

Erich reported that revision 2 of the SMC was distributed at this meeting. 
It also will be in the next mailing.  Because of the changes in the SPC
mentioned above, Erich will move the attached medium changer information from
the SPC to the SMC.

Erich Oetting moved that SMC revision 2 be accepted as the X3T10 working
draft for project 999-D.  Ted Lappin seconded the motion.  The motion passed
unanimously.

8.18  Directly-Addressable Device Interface (DADI) Status {Project 964-D}
      [open]

Larry Lamers told the committee that he will move to terminate this project
at the November meeting unless an editor is named.

8.19  SCSI Common Access Method -2 (CAM-2) Status {Project 990-D} [Dallas]

This project is still on hold, waiting for CAM to forward to second public
review.

8.20  SCSI-3 Controller Commands (SCC) Status {Project 1047-D} [Penokie]

George Penokie reported that there have been two meetings since the last
Plenary.  Most of the work being done at this point is editorial.  The most
significant change was changing "disk" to "storage."  Revision 2 was
distributed at this meeting.  George reported on a tutorial he gave earlier
this week.  George reported on the few changes between revisions 2 and 3 of
the SCC.  Revision 3 of the SCC is almost ready for forwarding.

George announced that the SCC meeting in October is being canceled.  The next
SCC working group meeting will be in November.

George Penokie moved that SCC revision 3 be accepted as the X3T10 working
draft for project 1047-D.  Charles Monia seconded the motion.  The motion
passed unanimously.

8.21  Multimedia Command Set (MMC) Status {Project 1048-D} [Harris]

Norm Harris reported that revision 1.0 of the MMC was in the last mailing. 
It adds about twenty commands, mostly suggestions from the ATAPI effort. 
Norm described the working group meeting held earlier this week.  Norm
reported satisfaction with the comments that he is receiving.  Norm said that
an issues list will be circulated on the SCSI Reflector.

Norm announced that revision 2 of the MMC will be distributed in the next
mailing.  Norm requested that anyone with comments contact him by September
26th.  Tom Hanan suggested that the ATAPI reflector be polled for comments
on MMC commands.  Norm agreed to do that.

8.22  SCSI-3 Fast-20 Parallel Interface (Fast-20) {Project 1071-D} [Lamers]

John Lohmeyer announced that the Fast-20 project is approved and that the
project number is 1071-D.  Larry Lamers reported that the task at hand is
preparing a working draft for the next mailing.  Larry said that he intends
to have a Fast-20 document ready for the next mailing, but that he is not
certain that it can be done.

8.23  XOR Commands Study Group [Houlder]

Gerry Houlder provided written minutes for the XOR commands study group
meeting held on Monday, September 12, 1994.  Gerry's minutes for the
September 12 meeting can be found in document 94-199r0.

9.    Old Business

9.1   Technical Information Bulletins

George Penokie reported on two comments made by Gene Milligan against the Log
Sense TIB.  An editorial comment noted that the RECL bit must be set to
solicit unit attention.  A technical change eliminated repeated reporting of
a counter overflow conditions.  George moved that the revised Log Sense TIB
processed via a letter ballot for forwarding to public review.  Gene Milligan
seconded the motion.  The motion passed unanimously.

Ted Lappin reported that no comments have been received on the Sequential
Access TIB since it was distributed in the last mailing.  Ted recommended
that John Lohmeyer process the Sequential Access TIB in a letter ballot for
forwarding to public review.  John took an action item to conduct the letter
ballot on the Sequential Access TIB.

9.2   Resolution of SAM Letter Ballot Comments

Charles cited 94-173r1, a document that lists SAM comments and resolutions. 
Charles explained that the working group had reviewed the comments and
resolution.  With two exceptions, 94-173r1 correctly represents the
resolution SAM comments.  The two exceptions were handled as amendments to
94-173r1.

Charles discussed an amendment to the comments and responses in 94-173r1. 
The amendment covers the identification tasks that are aborted out of a task
set.  Charles moved that the amended text be approved.  Peter Johansson
seconded the motion.  The motion passed unanimously.

Bob Snively next reported on a discussion of another amendment to the SAM
responses in 94-173r1.  Bob presented a new document that covers the
amendment, 94-189r0.  George Penokie moved that 94-189r0 be approved as
amended for inclusion as a letter ballot comment resolution for SAM.  Jim
McGrath seconded the motion.

Ralph Weber noted that the proposed bit usage in the Standard INQUIRY Data
conflicts with existing bit definitions.  Bob agreed to leave definition of
the actual Standard INQUIRY Data bit position to the SPC editor.

Jim McGrath asked that SCSI-2 and SCSI-3 behaviors be identical in specific
portions of the 94-189r0 proposal.  Jim McGrath moved to amend 94-189r0 to
change a SCSI-3 usage of ACA to the SCSI-2 CA.  Gary Stephens seconded the
motion.  The motion to amend 94-189r0 failed 5:19:0:23.

The motion to accept 94-189r0 was approved 23:3:0:21.

Charles reported that a previous change failed to reflect the intent of the
committee.  The wording changed in SAM clause 6.1 was changed to read:

   "Validation of CDB parameters is a logical unit option."

Charles proposed that the wording be corrected to reflect the committee's
intent as follows:

   "The checking of reserved fields in a CDB is a logical unit option."

Ron Roberts moved that this change be accepted.  Larry Lamers seconded the
motion.  The motion passed unanimously.

Gary Stephens moved that:
 -    the responses to letter ballot comments be accepted, and
 -    the several substantive comments made since the letter ballot be
      accepted.

Larry Lamers seconded the motion.

Bob Snively moved that Gary Stephens' motion be amended to include
instructing Charles to remove the dual port information added in revision 15
without prohibiting dual porting.  Jim McGrath seconded the motion to amend. 
The motion to amend passed 22:4:0:31.

The motion, as amended, required that:
 -    the responses to letter ballot comments be accepted,
 -    the several substantive comments made since the letter ballot be
      accepted, and
 -    Charles be instructed to remove the dual port information added in
      revision 15 without prohibiting dual porting.

The amended motion passed with a roll call vote as follows:

The following statements were offered by those voting no:  Jim McGrath voted
no based on the ACA handling discussed earlier in this meeting.  Jim McGrath
also found the resolution of the mandatory vs. optional letter ballot comment
was unacceptable.  George Penokie said that his no vote was based on 1) a
standing policy for not forwarding documents that he has not read and 2) the
removal of the dual port seemed inappropriate.

As a result of the motion, Charles Monia took an action item to create a SAM
revision 16 based on the accepted changes and John Lohmeyer took an action
item to forward SAM to X3 for further processing (first public review). 
Larry congratulated Charles on reaching this milestone.

9.3   Resolution of FCP Letter Ballot Comments

Bob Snively stated that all letter ballot comments have been resolved in FCP
revision 9.  Bob proceeded to describe a non-letter ballot comment regarding
cleanup during abort functions that affect multiple tasks.  Bob noted that
the latter comment is not fully resolved at this time.  Bob called on Gene
Milligan to present a unanimous recommendation of the working group.

Gene noted that his proposal is analogous to actions taken relative to the
P-cable during work on SCSI-2.  Gene moved that editor be instructed to add
the following statement to clause 7.1.2.2 of the FCP:

   Note:  X3T10 plans to consider recommendations from industry groups and
   other contributors resulting from early implementations and evaluation of
   FCP (e.g. a definition of the Abort Task Set, Clear Task Set, and Target
   Reset functions, in FCP, which may eliminated associated recovery abort
   functions generated by the target) in a future version of FCP.

Bob Snively seconded the motion.  The motion passed 37:0:0:20.

Bob Snively moved that the substantive changes made after the letter ballot
be accepted and that the revised FCP be forwarded to X3 for first public
review.  Larry Lamers seconded the motion.  The motion passed on a roll call
vote:

9.5   X3T10 Procedures [Lamers]

Larry had not found time to draft the proposed procedures.

9.6   Annual Publication of Documents [Milligan]

Gene Milligan distributed a document describing his proposal for annual
publication of X3T10 documents.  Gene presented the highlights of the
proposal.  The proposal has three parts; a background, a policy statement,
and proposed procedures to implement the policy.  By way of background, Gene
noted that timely delivery of standards is critical to this industry.  Gene
described how X3T10 can deliver standards in a timely manner without
violating X3 procedures.

Gene requested a X3T10 letter ballot for the proposed procedures.  John
agreed to conduct the letter ballot.

10.1  Resolution of ATA-3 Letter Ballot Comments (94-165)

John Lohmeyer reported that the ATA-3 Project Proposal (X3T10/94-019 r4)
passed: 51:0:0:9.

The Yes ballot from Peter Brown of Oak Technology included the following
comment:

   "I think that the initial proposal offered a better partition and would
   be more useful to people attempting to build products adhering to the
   specifications. I further think that the reason that the proposal was
   changed was an attempt to orphan ATAPI.  I object to this tactic."

The following organizations failed to return their ballots:

AMD, CMD, Compaq, Fujitsu, Harbor Electronics, Hitachi, Linfinity Micro,
Qlogic, and Quantum.

Larry Lamers reported that the ATA working group decided not to address that
comment.  John Lohmeyer took an action item to forward the ATA-3 project
proposal to X3 for further processing.

10.2  Resolution of ATAPI Letter Ballot Comments (94-166)

John Lohmeyer reported that the ATAPI Project Proposal (X3T10/94-022 r4)
passed: 48:3:0:9.  X3T10 is obligated to attempt to resolve the negatives.

The No ballots from Scott Smyers of Apple, Peter Brown of Oak Technology, and
Bob Snively of Sun Microsystems included the following comments:

   Apple:

      The use of ATAPI is primarily intended to be a "low-cost" interface for
      CD-ROM and tape devices.  I don't understand the concept behind
      "overlapped commands using a multi-threaded protocol."  This scope will
      have a direct impact on the development time, the availability, and the
      cost of ATAPI devices.

      We would like to maintain ATAPI as a "low-cost", relatively simple
      interface.  We would request to remove item b) of the Recommended Scope
      from the project proposal, dated July 21, 1994.

   Oak Technology:

      I voted NO on the ATAPI proposal. I will change my NO vote to a yes if
      either the scope statement explicitly states that ATAPI may be used for
      hard disk drives or if 2.2.d is deleted.

      Although 2.2.d is ambiguous it could be easily argued that "other than
      traditional ATA devices" excludes ATAPI HDD's.  Section 4.1 and 4.2
      points-out the possibility of "nonstandard evolution or revolution" in
      the case that HDD is specifically excluded from the spec. The scope of
      the document should accept the inevitability of ATAPI HDD's.

   Sun Microsystems:

      I regret that I must vote no on the project proposal for the ATA Packet
      Interface as the proposal is presently worded.  By making the changes
      described in the following paragraphs, my vote would be changed to a
      yes vote.

      1) Section 2.2

      The last sentence of the clause now reads:

      "The application for the proposed standard does not require compliance
      with the SCSI-3 Architectural Model (SAM)."

      It is very important that the ATAPI definition provide a software
      interface that is compatible with standard SCSI devices and drivers. 
      At the same time, it is clear that ATAPI implementations integrate a
      large number of the functional interfaces defined by SAM.  For this
      reason, the referenced sentence should be rewritten to read:

      "The proposed standard shall define services and functions compliant
      with those visible to the application client defined by the SCSI-3
      Architectural Model (SAM).  An ATAPI device may internally implement
      those services in a manner that does not comply with the SAM."

The following organizations failed to return their ballots:

AMD, CMD, Compaq, Fujitsu, Harbor Electronics, Hitachi, Linfinity Micro,
Qlogic, and Quantum.

Larry Lamers reported that the ATA working group drafted responses to each
of the no votes.  During initial discussion of the draft responses, Doug
Hagerman questioned the concept of ATAPI being widely used as a protocol for
hard disk drives.  Based on that claim, Doug asked that ATAPI and the various
SCSI standards be made more compatible (not divergent).  Gene Milligan said
that he does not believe that ATAPI will not be widely used for hard disk
drives.

The gist of the argument seemed based on different perceptions of ATAPI
goals.  Some of those present wanted very close alignment between ATAPI and
SCSI.  Others desired a clear separation of ATAPI and SCSI.

Larry Lamers moved that the ATA working group proposed responses to the three
no votes be approved by X3T10.  Joe Chen seconded the motion.  Ed Gardner
moved to divide the question.  Jim McGrath seconded the motion to divide. 
The motion to divide the question passed 12:7:0:38.  This resulted in three
motions, one for each response.  Each motion (to accept letter ballot
responses) requires a 2/3rds vote to pass.

Larry Lamers placed the response to the Sun response up as the first portion
of the divided question to be voted upon:

   The ATAPI project proposal does not claim to be an SCSI-3 implementation
   and, therefore, it is not required to be compliant with SAM.

   It should be noted that as much commonality as practical will be
   maintained between ATAPI and SCSI command structures.  However, there are
   inherent differences between ATA and SCSI which have to be considered.

This was sufficient to re-ignite the "What is ATAPI?" debate.  The divided
motion to approve the Sun response failed 23:9:0:26 (by a show of hands),
because a majority of the X3T10 membership did not support the response. 
Steve Finch and Gene Milligan requested a roll call vote.  The Chair allowed
this request even though it is somewhat irregular to change the voting method
after the vote is taken.  The results of the roll call vote were:

The motion still failed (now lacking both 2/3rds and a majority of the
membership) and the response was sent back to the working group for further
consideration.

John Lohmeyer placed the Apple response up as the second portion of the
divided question.  The motion to approve the Apple response passed 36:0:0:22.

The approved response was:

   "We share your goal of maintaining ATAPI as a 'low-cost' relatively simple
   interface.  However, there has been a need expressed to investigate
   enhancements to provide overlapped command capability.  We invite your
   participation in the investigation to help us achieve our mutual goal."

The Oak Technology response was the last part of the divided question to be
considered.  Gene Milligan moved to amend the motion to replace the proposed
response with the following:

   "X3T10 has considered your comment and elected to endorse again the
   statement in section 2.2d."

Steve Finch seconded the motion to amend.  The motion to amend passed
35:2:0:20.

The amended motion to approve the response passed 31:3:0:23.

10.3  ECMA [Cummings]

Roger Cummings presented an overview of the ECMA and how it might be applied
to X3T10 and X3T11 documents.  The committee discussed the advantages and
disadvantages of working with ECMA in the European standards making process. 
Some concerns were voiced regarding applying the ECMA standards process to
X3T10 activities.  No resolutions were requested or taken.

Roger asked for support from the ECMA member companies by December 1994. 
Roger said that he will continue pursuing this process as a private
individual.

10.4  Reserve & Release in SPC (94-106r2) [Weber]

Ralph Weber presented several editorial revisions to 94-106r2.  Ralph
presented a proposed change that would have the WRITE BUFFER blocked by
extent reservations.  Ralph, Jim McGrath, and Gary Stephens discussed how
WRITE BUFFER can affect extent reservations by downloading microcode for the
SCSI device.  After that discussion, the committee accepted Ralph's
recommendation that extent reservations always block the WRITE BUFFER
command.

Ralph moved that 94-106r2 as revised be approved for inclusion in the SPC. 
Jim McGrath seconded the motion.  The motion passed unanimously.

10.5  FORMAT MEDIUM Command for SSC (94-146r3) [Cummings]

Jeff Williams moved that 94-146r3 be accepted for inclusion in the SSC. 
George Penokie seconded the motion.  The motion passed unanimously.

10.6  Working Group Recommendation on SDTR

Gene Milligan moved that X3T10 endorse the recommendation of the working
group to change SIP so that a SDTR message transfer period factor value of
12 would mean a 50 nanosecond transfer period.  Skip Jones seconded the
motion.  The motion passed 25:4:0:28.
