Not that I know of. Why do you ask?
Does it look like the one in the photo on that site? Sounds like a very cool artifact. You can't always tell much from the serial number -- for example, notice that they started their model numbers with '200,' just to make the company look bigger and more reputable.
There are a few HP 200As listed on eBay in the $100-$300 range. Not sure if they're actually selling for that, though.
