1.0     Opening Remarks
Ron Roberts called the meeting to order at 9:20. He thanked our host, Charles
Monia and Digital Equipment Corporation, for hosting the meeting.

It was stated that the meeting was authorized by X3T10 and will be conducted
under the X3 rules.  Ad hoc meetings take no final actions, but prepare
for approval by the X3T10 technical group.  The voting rules for the meeting
are those of 
the parent committee, X3T10.  For the ad hoc, other than straw votes, the
voting rules 
are:  one vote per participating company. 

It was also stated that the minutes of this meeting will be posted to the
X3T10 BBS, the
SCSI Reflector, the MMC Reflector, the ATAPI Reflector, and will be included
in the next 
X3T10 committee mailing.

Attendance at working group meetings does not count toward minimum attendance

requirements for X3T10 membership.  Working group meetings are open to any
person or
company to attend and to express their opinion on the subjects being

5.0      Approval of Agenda
The agenda was approved as modified.

6.0      Agenda
6.1      Philips CD-R write process
Philips and H-P presented new write functional flows for writing a CD-R.
After discussion
it was decided to have HP (Rob Simms) document their presentation to be
included in
Rev 3.0. The editor agreed to update the Rev 3.0 version with the
6.2      Review revision 3 of MMC doc
The working group reviewed the command formats, in the document, from the
of comparing them to those in ATAPI 2.4.  The editor required definition of
some tables to 
be included in Rev 3.0. The working group requested that all tables
identified by the editor 
be included in Rev 3.0.
The working group also reviewed the list of commands and determined which
should be listed as mandatory or optional. It was noted that commands that
may be mandatory
in the parallel SCSI devices, may not be mandatory when using CD based
devices. The solution 
was to place an asterisk next to those M/O definitions that may be different
in the MMC 
document. Rev 3.0 will contain some of these indications.
The next meeting should be devoted to the detail review of the Rev 3.0
document, in
preparation for forwarding the document for first public review.
