A lot of that stuff I've seen before in Mark C's coffee.....
That's what was spilled on the board in the first place hehehehe
That board *IS* repairable, laborous yes, but repairable.
I'd be more inclined to use solid copper (insulated-telecom) wires to bypass all the crappy pads/tracks.
I've done a lot worse cpu boards than that, and had them up & running in around 2-3 hours.
Lock the doors, phone off-hook, head down, bum up, you CAN do it !!
