~ I'm not sure where the other MSD's die, but I know the 7A i ran a few
~ years ago got flaky as hell at 10V and totally crapped out by 9.5V.

People I have talked to in the past has also seen the flaky response
around the save battery voltage.  What I have also been told is that
MSD boxes usually don't just "die" - they act screwy instead, like 
mis-firing, etc.

The ONLY plus I give to Jacobs box is a toggle switch (3 position)
which can switch you back to normal un-mod mode.  The third position
kills the ignition.  Jocobs could do this because the stock ignition
amplifier is retained, the Jacobs box is inserted between the
amplifier and the coil.  MSD takes over the job of the ignition
amp by hooking directly to the reluctor pickup, so this is harder
with MSD.
