6.0      Meeting Agenda
6.1  - SONY CD Text presentation
Masayuki, presented a proposal for implementing CD Text within MMC II 
command set.  The results of the long discussion involved asking 
Masayuki to complete the following items.  

The proposal for CD text needs to include the reading 
and writing CD Text data.  Writing CD text must address the 
cue sheet and associated data type formats.  Reading CD text 
must address synchronization issues associated with reading 
CD text while playing.

6.2  - Write 12 command 
The group reviewed the Mt. Fuji 2,  Write 12 command. The bit 
description of EBP will follow the definition in SBC with a note 
about the C/DVD issues. 

6.3  - Get Configuration Cmd
Bill McFerrin presented his version of the get configuration command.
This command uses bits in the response data to define which commands
and mode pages are supported by the device.  Rob Sims and Devon  
Worrell strongly opposed this approach that conflicted with the 
Mt Fuji 2 command.  A vote on accepting this command will take 
place at the next meeting.

6.4  - Joint Meeting with DISKBOYS & SPC2 WG 
Pete Mclean presented the following four items:
    1. New device type for devices attached to SBP-2.
    2. Proposal so that SPC-2 accommodates new device type.
    3. Define other commands in device type document
    4. Help on isochronous.

Peter Johansson presented the following details about the new device 
type:
    1. There will be one Mode page.
    2. Send diagnostics to be made optional
    3. Request sense to be made optional
    4. Inquiry to be made optional
This prompted a long and involved discussion that informed the SPC2 and 
MMC II groups concerning the approaches being taken by DISKBOYS.   
 
6.6  - MMC I comments
Janne Siren of Nokia Telecommunications pointed out two editorial issues 
in MMC I as follows:
1. In section 5.1, table 11 "CD Command Listing" incorrectly identifies 
SPC as the document with information concerning Seek(6) and Seek(10).
The correct document is SBC.
2. In the informative annex example cue sheet are not correct. In the 
example cue sheets lead-in and lead-out the data form should be 01 not 
00. 
Both items were accepted.
