Hi Ron.
Thanks for the confirmation. I figured out that Rev A was a mistake, after
looking at the fan connector and fan supply orientation. Had Rev A been used
it wouldn't have been a disaster, but the mod would have had no effect, as
it connected both ends of the capacitor to the positive fan supply! Oops! I
haven't seen any errata but it doesn't matter now.
My KPAIO3 module isn't the same layout as the ones shown, but the actual
connections are the same to the fans.
Well, I completed all of the mods, so now to put it all back together. <g>

Hi Alan:
Use Rev B. Rev A of the instructions had an error that was corrected by an
errata. Apparently you don't have that errata. The change was subsequently
included in the Rev B printing.
