So I guess we need a multi-seat time machine.....
The vector games had not a great range to the brightness, turn them up just a little
and the lets call the reposition lines would begin to show..... So you could not turn
them up to the point of damaging the screens.... The only bad thing was that when
they were on, stuff like top score, and game title were displayed in the same spot,
the teaser stuff. But I never saw a vector game with a weak, or damaged screen...
And you are right, the guns were on only while painting the lines on the screen..... Bright
as you want, still on only .001% of the time of a scan line set for their entire life....
