doohoo

I recently picked up a large collection that belonged to a subject who passed away. While going through the games i located 4 carts that were a little different at the bottom of the box. Iv been told not to test them and to possibly try to dump them. I have no clue how to do that though. Any thoughts on value, history, or authenticity? I'm currently working a night shift and cant get pictures of the boards until in the morning.
