[Coco] Gold Plating the Tin Card Edge Fingers of Old Coco Paks, MPIs, etc.

[Kip Koon]

Hi Everyone,

I'm having great difficulty keeping my Coco 3 compatible MPI operational.
It worked fine yesterday.  I disassembled my Coco 3 setup to test some other
cocos and when I set my Coco 3 setup back up with the Coco 3 MPI later on,
it was a no go.  The Coco 3 will not boot up, even with no paks plugged into
the MPI.  It'd just the Coco 3 and an empty MPI.  I looked at the card edge
contacts and they are awful! Yuck!  No wonder it isn't working!  How do I
revive those card edge fingers plated with tin.  It is possible to have them
gold plated somehow without completely removing everything from the PCB?
Any ideas would be greatly appreciated.  Thanks in advance.
