[Coco] eBay MPI Heads Up (and how damage can be done)

[K. Pruitt]

Actually that article isn't the one that was discussed earlier on the list. 
The one you found is a newer one.

It's not the technical article I was thinking of, but a piece of information 
in the new article allowed me to determine which switch position is which. 
That'll make testing a lot easier. I printed out the new article and put it 
in a binder with Marty's previous article on the subject.  Definitely must 
read stuff for the Coco hobbyist.

Thanks.
