Lots of technical information on this dead-end game platform. This is one of those things that I didn't let slip past me, like the PXL-2000. Instead I found it being remaindered and picked up the device, all the accessories, and all the games the store had for about a hundred bucks. The two main drawbacks I see in this design are the monochromatic display and it is impossible for someone to watch you play. Even with a Gameboy you could watch over someone's shoulder.
AtariAge sells new and vintage games and hardware for the entire line of Atari videogame systems and home computers.
Supplier of such essentials as the USB programmable cart for the Atari 5200 game system -- just install a game over the USB cable and plug it in to play.
