Hi Raj and all,

I finally hear back from the owner of the scsi to sd  he said the V6 is a
little too fast for slower hardware so he recommended the
V5.  With the CMD HD's external power source I would only need maybe just
the 5VDC only.
Was the 12VDC only needed for the actual mechanical mechanisms motor only?
If so I would just of course need to cut the 12VDC wire since that is no
longer needed, Im referring to the small
wire with the larger connector (for hard drives) well and a ground wire is
needed for that too I suppose. :)

 With the scsi to sd board does this come with seperate software for
adjusting certain settings etc and is that then flashed into
the firmware?  Can the firmware on this board be updated etc?
Mainly for the CMD HD though only uses Dev0 and Lun0  so will this firmware
let you select this scsi ID number
since because the CMD HD only uses zero, otherwise other numbers will just
create SCSI errors.

  So again Im awaiting an answer from this guy, as far as the power
requirements, and how to configure the
scsi. If I understand the info on this it appears its a PC app that you
select all of the scsi settings to use with different types
of scsi, or is this just limited to 50 pin scsi, it looks like only 50 pin
to me.

Anyway thanks guys once I hear from this guy I will try the V5 one is what
this guy reccomended for slower drives, but
will the V6 compensate for Jiffy Dos and a Super CPU. :-)  If so maybe hes
wrong and I pointed that out to him about Jiffy Dos and the
Super CPU helping, but I would want it to still work at 1mhz though, but
this was just something I was curious about.

Thanks for your suggestions.

Terry
