Our slot expert, John Robison, who wrote the answer to the earlier question, responds:
As far as I know, every Class II machine has to have the ability to display the bingo card that is used to determine the outcome. The player might be able to control whether the bingo card is displayed. The player may also have the ability to change the bingo card. The Help screens may also display the winning patterns and how much they are worth.
I found some videos of Class II machines on YouTube. Note the bingo card displayed in the bottom-left corner in the image below.
