Richard,

Correct.  However, SPI-2 uses Fast-5 throughout the document for what
SCSI-2 called 'synchronous' and what SPI called 'slow'.  If we had had a
lot of foresight, we would have called the speeds Sync-5, Sync-10, Sync-20,
etc.  Since "Fast-xx" terminology is rather engrained at the moment, I
think the Fast-5 term is a reasonable way to designate 5 MByte/sec transfers.

If you really don't like this convention, there is a SPI-2 editing session
scheduled for Dec 3rd in the Irvine area.  George might be hard to convince
on this one, however.

John
