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.
