Fairchild Channel F Protos aquired

[extrarice]

Over the weekend I picked up a Fairchild Channel F system and 25 or so games. When I got home I started looking at the cartridges and noticed that one had an interesting label: "Not FCC Approved. For Demo Purposes Only. Not For sale." I decided to open up that cartridge to take a look, and found what I assume to be a prototype of Numbers Up. I haven't powerd up the system yet so I don't know if it still works. Click on the thumbnails to see a larger picture (or go straight to the directory here







Some of the other cartridges did not look like production Channel F boards, so I'm not sure exactly what these are. I have two or three other carts that look like this:







I contacted the seller and he told me:

"We are the original owners. My dad was part of a team of engineers that developed the game when he worked at Fairchild. That is how we got the game with those particular cartridges. Hope you get it up and running."

Hope you got it at a good price ^_^

The system, 20+ game carts and game carrying case set me back $25. Even if the system doesn't work, it's still just a bit of change spent to get something unique.

So any ideas on what that second set of pictures is?
