I was in the process of cleaning and recapping an SE/30 logic board which had been subjected to a battery leakage.
I've checked and rerouted all the rotted traces (totalling about 15) between the RAM, ROM, VROM and GLU but when I was satisfied enough to attempt a boot, pin 63 on the ROM burnt out (causing pin 64 to fall off, but pin 63 was definitely the offender) leaving me with a dead SE/30.
Any ideas what might have caused the sudden burning on the ROM? I've checked it in another machine and now it only boots a grey screen with death chimes.
Maybe there is a short I haven't noticed, or there are broken internal traces too?
Any suggestions are much appreciated, but I fear this machine is un-repairable.
