Re: monitor degaussing

This brings up an interesting question I had the past 5000 miles to
ponder as I have just returned from a "drive all over the planet"
vacation. My conversion van has a standard "tube" monitor in it... How,
come I can drive all over creation with it, and never have a degaussing
problem, but when I move an arcade game across the room it becomes a
mess? What is different in a newer TV vs a newer monitor (be it vector
or raster)

And why degauss off? My electronics teacher taught us to do it on
