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...
