[Coco] IT"S ALIVE!!!

[Mark Marlette]

As I am sure this is all possible, I have never seen this happen on a properly extracted/handled chip.

Not to say that you guys didn't properly extract/handle, you could have and it was damaged prior.

These are J leaded components. You have to apply force away from the pin to get it to move as it is wrapped under the body.

Taking a GIME out without the proper tool, cant be done properly, period.

Not preaching, have done over 1000 CoCos easily. This is VERY rare to have a GIME fail, in any manner. Dirty contacts, common as heck.

That is why they call them statistics though...it is bound to happen. :)

Great story and not that unusual I'd bet. The same thing happened to me with a 
GIME chip.

In order to test software that gave the Coco3 a "run for its money", I would 
exchange the two GIME chip versions to see how the GIME chips differed. This was 
with regards the search for the "256 color mode". I did this once too often and 
broke a pin off the newer GIME as it came out of the plastic.

Luckily there was still a small amount of metal visible which I could expose 
further by scraping away some plastic with a knife blade. With the GIME inserted 
in the socket, I placed a short piece of copper wire into that portion of the 
socket so that it made contact with both the socket and residual pin.
The Coco3 worked perfectly!
