So... there's only been 9 Atari 7800 Prototypes found and played?

@Cousin Vinnie don't forget about California Games.

Arthur Krewat mentioned at one point that he may even had some of it working.

 

Art and I talked about Cali Games at length. I even send him a dev unit to work with. He has at least some of it on old disks and some of the code printed out on paper still. The BMX portion was working as I told him I'd be happy with even just that event running on it's own. It's been a couple years since I last conversed with him though. He has a dev unit if he ever did decide to crack into it. I made sure that was not a hurdle for him to have to worry about. He signed a bunch of games for me too.

So only 9 still. 

The rest are all rumours and dreams. 

Looks like 10 now since Sentinel NTSC was an unreleased prototype.  Anything else that pops up in the flesh for the rest of us sinners will be awesome to see.

I really hope we can one day see prototypes of Moon Patrol and Elevator Action pop up, as well as maybe that original version of Jr. Pac-Man.

The one and only Pole Position built in Bios exists too... I own it 😉

What about 7800 basic or writer or some crap? Was  that a thing too?
