I'm not sure myself.  never tried it. ^_^;

Thats interesting.  I will have to try that some time.  Right now, my chain has
the CDRW after the Syquest, and I never figured in the potential sync problems.
However, I recall one of my friends mentioning that 10M/s should not be possible
because the compact connector on powerbooks is missing those extra 12 or so pins
needed.  Maybe the Orb is reporting 10, but falling back or compensating for the
lack of pins.  Or maybe connectors have changed.  My chain's Syquest has a
Centronix connector, my RW has a 50 pin mini-trapezoid.  Could explain some
things.  Whatever works i guess.
