[Coco] Melted Keyboard Repair

[Kevin Becker]

That is a great question.  I was hoping someone else had experience 
repairing this before I dove in myself but failing that I took the 
plunge.  I'm planning to get out my calipers and measure the holes, then 
try to find a set of very small screws.  I think I should be able to 
carefully drill some small pilot holes and screw it all back together.  
It will be tedious but seems doable.
