I am trying to track down a SCSI issue with one of my boards here

Thought it would help, especially when your following the schematics doing continuity checks

as am right now   🙁

ok looks like i saved the day,

needed to run a wire from P24 of GLUE to P17 of the SCSI I/C 

this line was called SCSI*  ---whatever that means.

It works now.  Techkinght provided some words if inspiration so cudos to him as well.

Other common lines that are out from cap rot are as Follow's:

P66 Glue to P19 SCSI I/C

P68 Glue to P18 SCSI I/C

P51 Glue to P9 SCSI I/C

Also some other Semi Common lines that are out effecting SE/30 SCSI:

P5  SWIM to P27 SCSI I/C

P8  SWIM to P26 SCSI I/C

P15 SWIM to P21 SCSI I/C

Great job uni. It looks like I need to do something similar. I've got 10 missing signals to patch on mine.
