one is known to be working but several pins are detached and the golden traces are not there, has anyone ever restored something like this ?

Yikes, looks like a real pickle.

It might be able to be done but would be fiddly. If solder doesn't take to the golden traces and or the heat damages them then I guess not. It looks like a few traces have all but disappeared back to the can edge.

You might be able to glue the contacts back on and run very fine wire from the gold trace to the contact. I don't know how the glue will react to heat.

I notice there is an extra finger on the MTRS WPS and HDS contacts for the CRC. I wonder what this was supposed to be for. The 65 even has a contact pad for it on the circuit board but goes nowhere.

I wonder if it would be feasible to add an extra Forum category for repair topics. It might be easier to look up items later on.

cheers
