My last attempt really messed up some text. Someday I'll learn how to send
my files through my system(s) and across internet and not screw it up.
Here is another try. Sorry for the inconvenience...

Subject: Proposal for Proposed Project -- ATA3-PH
_______________________________________________________________________
Per the agreement of the ATA Working Group meeting on January 10, 1994,
I am submitting this project proposal as one of four new projects which
will constitute the work on ATA-3 standards. I request that the
discusion and, hopefully, forwarding of these project proposals be
accomplished at the March X3T10 plenary meeting.
Respectfully,

1. Identification of Proposed Project
1.1 Title: ATA-3 Physical Interface (ATA3-PH)
1.2 Proposer
This project is proposed by the X3T10 Technical Committee. For
additional information, please contact John B. Lohmeyer, X3T10 Chairman,
at NCR Corporation, 3718 N. Rock Rd., Wichita, KS 67226 (Phone: 316-636-
8703 FAX: 316-636-8889) or Dal Allan, X3T10 Vice-Chairman at ENDL, 14426
Black Walnut Court, Saratoga, CA 95070 (Phone: 408-867-6630 Fax: 408-
867-2115).
1.3 Date Submitted: January 14, 1994
1.4 Project Type: Development
2. Justification of Proposed Standard or Technical Report
2.1 Needs
The draft standard for AT Attachment has been completed and the draft
for the ATA Extensions (ATA-2) is near completion, but as the popularity
of the interface has increased, its application area has grown outside
the originally intended purpose of direct attachment of small disk
drives to desktop computers.
ATA-3 is needed to continue to broaden the scope and application area of
the ATA interface and to take advantage of the huge installed BIOS
(Basic Input/Output System) base, and software. Support is needed for
traditional HDD devices plus additional devices such as CD-ROM and tape
devices. It is expected that the SCSI-3 command sets can be used for
these new device types. In addition, support is also needed for
removable media devices and expanded number of cabling options. The
resulting increase in complexity has made it desirable to divide the ATA
standard into a hierarchical set of standards, of which the ATA-3
Physical Interface is one.

2.2 Recommended Scope of Standard or Technical Report
The proposed ATA-3 Physical Interface standard shall maintain a high
degree of compatibility with the AT Attachment while providing
documentation for new capabilities including the following candidates:
a) Provide a means to support the AT Attachment protocol on a variety
of physical interfaces such as that for the newly-emerging requirements
for memory cards.
b) Other capabilities which fit within the general scope of
implementing the AT Attachment Interface on a broader range of
applications.
This proposed standard is not intended to require changes to presently
installed devices or existing software. It is intended that this
proposed standard would be used to provide additional capabilities.
2.3 Existing Practice in Area of Proposed Standard or Technical Report
The proposed project involves evolutionary expansion of the draft AT
Attachment standards to provide additional capabilities.
2.4 Expected Stability of Proposed Standard or Technical Report with
Respect to Current and Potential Technological Advance
The nature of the proposed project is to insure that the AT Attachment
has an upward, highly compatible growth path. This will insure that
current investments in AT Attachment are provided with more stability in
the face of technological developments.
3. Description of Proposed Project
3.1 Type of Document (Standard or Technical Report): Standard
3.2 Definition of Concepts and Special Terms (if any): none
3.3 Expected Relationship with Approved X3 Reference Models (e.g., DBMS,
OSI)
The ATA-3 Physical Interface standard is for use in closed systems.
3.4 Recommended Program of Work
The following program of work is planned for the ATA-3 Physical
Interface standard:
o Solicit continuing participation by the present AT Attachment
participants through X3T10 procedures and new participants through press
releases. Invite comments by end-user organizations and invite
proposals from organizations that may have a contribution to a viable
ATA-3 Physical Interface standard.
o Establish functional requirements for ATA-3 Physical Interface
functional additions along with downward compatibility requirements.
o Prepare a draft standard based on proposals submitted and other
information gathered during the initial investigation.
o Consider the results of ATA3-Physical Interface testing as may be
available to the committee through the voluntary efforts of the various
participants in X3T9 and its assigned task group.
o Submit the draft proposed standard to X3 for further processing.
3.5 Resources - Individuals and Organizations Competent in Subject
Matter
The current membership of X3T10 includes representatives from all parts
of the computer industry from semiconductor chip manufacturers to large
mainframe system manufacturers as well as Government agencies. The
members of X3T10 have expressed their desire to participate and
cooperate in the development of this proposed standard.
There are sufficient resources to complete the development of this
standard without delaying work on other standards.
3.6 Recommended X3 Development Technical Committees (Existing or New)
It is recommended that the development work be done in task group X3T10
which is responsible for developing the draft ATA Extensions standard.
3.7 Anticipated Frequency and Duration of Meetings
Task group X3T10 meets for two days bimonthly. Specific task ad hoc
groups are called as may be required for one to three days between the
regular meetings but their results are not binding.
3.8 Target Date for dpANS to X3 (Milestone 10): December 1995
3.9 Estimated Useful Life of Standard or Technical Report
It is anticipated that this standard will have a life of over 10 years.
4. Implementation Impacts
4.1 Impact on Existing User Practices and Investments
The proposed ATA-3 Physical Interface standard will provide an upward
growth path complementary to the existing practices and investments. It
is likely that any isolated negative impacts would occur in any case
through non-standard evolution or revolution.
4.2 Impact on Supplier Products and Support
The proposed ATA-3 Physical Interface standard will provide an upward
growth path complementary to the existing practices and investments. It
is likely that any isolated negative impacts would occur in any case
through non-standard evolution or revolution.
4.3 Techniques and Costs for Compliance Verification
The committee will consider the results of ATA-3 Physical Interface
testing as may be available to the committee through the voluntary
efforts of the various participants in X3T9 and its assigned task group.
With this method all costs are borne by the organizations of the various
participants and have for the most part been mainly an adjunct of their
normal development costs.
4.4 Legal Considerations
No new legal considerations are expected that are not already attendant
with AT Attachment and in accordance with accepted X3 patent policies.
