If the TED is what is printed on it, it should work in any C16 or +4, so 
that would be easy to test and find out if it still works. It was also 
mentioned that the CPU has the lid only taped on... Which would make it 
easy to take a peek at the die.

I do have a working TED in ceramic, but whoever had it before me mounted 
a heatsink with expoxy, there is no way to remove it and find out if 
it's a 7360 or 8360. There are no diodes though.
