I picked up a SE/30 that had some pretty significant capacitor leak damage. I had a transistor at Q3 fall off the board from corrosion. I didn't initially see it, but I had pin rot on UE8 that lead to a jail bar pattern on the screen. I replaced Q3, and installed a brand new UE8, and the machine now boots with a good screen with no bars.
The next problem is that I can only boot from floppy (I used Floppy EMU and it boots into 6.0.8 fine) . When I try to use BlueSCSI to boot, I only get a solid red light on the BlueSCSI and the machine gives me a disk with a question mark. This is the same whether I use an external BlueSCSI or the internal connector with an internal BlueSCSI.
What should I try for troubleshooting. I'm not great at FloppyEMU and loading software (I typically use the BlueSCSI for that). Are there SCSI utilities I can use to see if the SCSI port is functioning. Are there chips on the board for doing SCSI I can inspect for pin rot? Traces I can inspect more closely?
