I'm a big fan of 'burn in' monitor
In my Galaxian cabinet for example, I've used a TV instead a real monitor... and I use to let that cab plugged for a long period.. in order to have 'HIGH SCORE' engraved on the screen
I use to think it would give more 'authenticity' to the whole things
Of course I do that when I'm in the game room, and because I have to admit that Galaxian is the game I play the more
Am I crazy doctor?
