Interesting. The most jarring info in this topic has been the American Coin scandal, of which I know almost nothing. Someone mentioned it, and it got ignored. That's pretty weird. Why wouldn't anyone ask about it?
Also, you'll notice there are no public records available of number of machines with chips "too old," or of malfunctioning chips in general, or what percentage of machines, if any, that have been found to have issues on an annual basis. Interesting what information is not available.
Gee, I wonder why.
