Those of you my age and older probably remember these old test patterns. Normally they were accompanied by a very annoying and steady beep. This one is from an Indianapolis station.
I remember getting up very early in the morning and finding these test patterns on the TV until about 6:00. I would be sitting there with my bowl of cereal and milk waiting for the test pattern to end and the cartoons to start!
