...and you haven't cut those two capacitors yet.  Shame on you.

(Dave pulls a disused DuoDisk out of the closet and removes the lid)

I remember performing the mod on a bunch of DuoDisks years ago, and I know
all of mine are "fixed"...in fact, I did both the mods on mine.  Let me
see if I can find the spot where the caps used to be...I think it was on
the analog board, which is above Drive 1...

(Dave pries the shield off the top of Drive #1 and takes a close look)

Yeah, there's the spot.  C29 and C30, located next to the two four-pin
connectors towards the center of the drive case.  Both C29 and C30 are
gone from my DuoDisk.  I've got documentation on that mod around here
someplace, but I remember that the reason for the mod was that the DuoDisk
likes to trash disks, especially copy-protected Pascal disks, when you do
an Apple-Reset.

It takes three screws to get to the analog board...two in the back of the
case, one in the shield.
