[Coco] Keyboard

[PaulH96636 at aol.com]

Look carefully at the keyboard connector ribbon to see if there are any  
breaks in the 
embedded traces leading to the connector.
I found a cut across one of them in a coco-1 years ago, as if a box cutter  
had been used
to open a box of keyboards before installation into the coco. After a few  
years of use, one
or more of the traces did open up, but I didn't try to fix it because I had  
just decided to buy
a coco-2.
 
However, perhaps if a cut is the problem, try using some nickel print or  
conductive paint
to regain contact. As I haven't tried this specifically on a coco kb, can't  
say how effective
this might be (seems the plastic coating covering the traces would need to  
be carefully 
scraped away to expose both sides of the break).
