All I did was change a 0 back to a 1. I wonder how the damn
parameter changed in the first place?
Anyway, I am really happy now. Really happy. I mean REALLY HAPPY!

Where I worked we had hundreds of devices that had microprocessors in
them. For no reason we could tell every once and a while one might do
something strange and would have to be reset. This may only happen once
a year or so.

When memory chips first came out, it was said that the coverings of them
might emit an alpha partical and flip a bit.
I figure it was a cosmic ray. Maybe my machine has a nuetrino detector
in it! 1 detection in many years fits the bill. How many years I don't
know but the machine has been around a long time. I could wrap the
machine in lead to protect it but I don't have any two light years
thick pieces.
