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

[George Ramsower]

Kip,

 What I have done in the WAY past is cut a gold plated edge connector off of a PC ckt board and soldered a short ribbon cable between it and the original together, after cutting the original connector somewhat shorter. This gives felexability and a new, gold plated edge connector onto that device. It isn't easy to plug it into a Coco connector, but it is doable. 
 Re-tinning the old edge connectors is possible if all the original copper is in place, enough to solder to.  I'ts a pain in the petuty but, doable. Clean and polish the old edge connector very well or the solder won't stick.

  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.

  Kip
