This is a retail-store demo NES console, the type you probably saw back in 1986 at your local Kiddie City or something. It's pretty huge, and you're supposed to put a TV on top of it. The things you can find at flea markets are really incredible sometimes.
The thing has two controllers, and offers a choice of 16 games: Tennis, Baseball, Soccer, 10-Yard Fight, Golf, Wild Gunman, Hogan's Alley, Duck Hunt, Wrecking Crew, Excitebike, Kung Fu, Super Mario Bros., Ice Climber, Pinball, Clu Clu Land, and Stack-Up.
The only button you have access to (besides the controllers) is a "Game Select" button on the front console that lets you switch through the available games. A LED lights up next to the title of the game you're currently playing on the console... and that's actually pretty much it from the outside. All the games are the same as their released counterparts.
Where this thing really shines is when you open up the unit. Inside we see an NES board (top right).. attached to a NES-to-Famicom adapter.. attached to the largest multicart ever made (well, in terms of physical size, anyway). The chips with white stickers on them are the EPROMs with the actual games inside them, and if I recall correctly they're socketed so you can replace the games easily. There are also several dip switches on the board.. the only one Mike's been able to figure out is one that automatically switches to the next game after about 4 minutes of playing any one game. (as a deterrent to kids playing the thing all day instead of buying NESes for themselves). It actually is a cool little unit, and shot of a Play-Choice 10 is probably the neatest piece of NES hardware that the general public didn't have access to.
