I finally got the time to change out the Bourns filter at RP10.

Man, what a hassle that was. It's in a really tight spot.

Anyways, it appears to have had very little effect.

The system still freezes on attempt to intialize a floppy - sometimes it'll throw a bomb error and restart.

I know it's not the drive because it's been tested in my Classic (and my Classic's drive behaves this way in the SE/30).

The issue also affects my external floppy when connected to the SE/30, but not when the external floppy is connected to the Classic.

I know it's not an extension causing the issue, as it still occurs if I boot with extensions off.

I have continuity between the RP10 filter and the ribbon connector port & external floppy port.

I have continuity between the RP10 filter and the SWIM.

I have continuity between SWIM and UH7.

I have no more ideas....  anyone have any suggestions?
