This is one of the very first Famiclones to be released in America, and it's also one of the few to get the hammer from Nintendo themselves. System is pretty much the exact same thing as the American NES. Soon after Nasa machines began to appear "legaly" outside of the United States in South America and the Far east. The second variation on the right was released a few years later (note the Genesis style controllers.) Not to hard to find on Ebay or at flea markets.
