Neat. If this was Westwood's dev kit, then it was probably used to develop DragonStrike.

This is an original Nintendo Development Kit. It came from the warehouse of Westwood Studios in Las Vegas, Nevada. Westwood was an early game maker that was eventually bought by Electronic Arts. I have plugged the item in and hooked it up. Nothing happens other than the screen blinks off and on with a white background. I have no idea if there is a game on it or not. The bottom portion of the kit works because I was able to run another game cartridge on it. The electronic board has ATARI printed on top of it in a few places. I think that is a little strange.
In 2001 I was working in Westwood's Storage Warehouse. The warehouse was a mess. I remember throwing out a bunch of random things including some Atari 2600 controllers and tons of old video game magazines. When I saw this item, I did not know what it was. My video game experience starts and stops at playing them. I knew it was odd so I asked if I could have it. My supervisor said help yourself to anything that's being tossed out. Since then it has been sitting in my garage where I have regarded it as a curiousity but also as a possible piece of video game history.
It is my opinion that this item is a one of a kind find for Original NES Nintendo Collectors. I set the reserve fairly high because I do not mind if it has to sit in my garage for another 10 years before I get a good price. If you have any questions I'll do my best to answer them.
