I've got a recapped Macintosh SE/30 board that I have been fighting with here and there over the years. It will boot into System 6 but will either freeze or system bomb on the ram test. Trying system 7 it will either bomb on boot or freeze on boot. I have tried many combos are verified ram Simms with the same result. Even replaced some chips too. I tried the new Reconnaissance application and it passes all the basic tests. I am at the point where I would preferably ship it out to someone to get it repaired unless someone sees something obvious to check. I am located in Canada, but willing to ship to the US if necessary if it comes to that point. Probably one pesky trace broken somewhere...
Macintosh SE/30 weird issues.

Can you provide some high-res pics of your logic board, top and bottom? Curious if there are any signs of corrosion. If you move the RAM from bank 0 to bank 1, is it the same issue still with failing to pass tests, or boot?
- There was not a whole lot of corrosion. The bodge seen was from me ripping a pad. Swapping from bank 0 and 1 or vice versa results in the same issues.

I can't tell from the photos, if it is light reflection or jpeg artifacts, but the lower half of the board seems to be covered in a lot of flux. Some flux is conductive and corrosive. From the CPU down to the external connectors looks pretty covered to me. Get some IPA and a toothbrush or cotton swabs and clean that up and see if that fixes your issues. Ultrasonic cleaner may be better, if you have one.
