SE/30 - SCSI and Floppy Not Working

Hey there,

I've had a random, sudden issue with my Macintosh SE/30. The SCSI bus and Floppy bus don't seem to be working properly. I've been using a BlueSCSI in place of a hard drive for a while and everything was working perfectly. I took the BlueSCSI out to update the firmware and when I tried to boot from it, the BlueSCSI wasn't getting any power. Powering it with the Molex connector works. I tried another BlueSCSI and same issue. Further, I also noticed that the floppy drive doesn't work anymore either. I tried my FloppyEmu and the Emu gets power and I can choose a disk to load, but selected a disk does nothing. I'm not sure what could have happened. I checked the logic board and it looks fine.

Can anyone tell me if they've encountered this problem?

I'm gonna make an educated guess that it's something in the SWIM controller as that's the only thing on the schematic that I can see that connects to both of them... either that or one of the voltage rails has gone perhaps? Have you probed it with a multimeter?
