Decode Kickstart failure by address lines?

Weird question.


I have an Amiga 3000 I'm working on. I (think I) have all of my board connections repaired, and have tested socketed ICs in another machine, but I'm about to do a deeper dive into why I'm not booting. I have a bit of a weird situation, and I'm hoping it might help me figure out where this fault is.


When I boot with a standard Kickstart ROM, I still get no video, but my address lines are very active.


When I boot with DiagROM 1.3 or 1.2.1, the machine will halt almost immediately, and the address lines are frozen in high or low state. Is it possible to use that value to decode where in the DiagROM it's halting, to see if it can help highlight a hardware failure?
