Looks to me like bad cables caused the heat that discolored the controller contacts. With any luck that is all it did. The bench test in the documentation will tell you allot, of it checks OK you need to replace all the cables with soldered connectors. In the process of doing that on my 512, looks to me like the Melex cables are just crimped and not soldered, time and corrosion makes for high resistance which makes heat.

If you do determine the controller is bad I would be interested in getting my hands on it. I am looking for a few bad 1204 controllers to see what it actually takes to repair the durn things.
