That's definitely a piece of gaming history you have there! However, you can't always expect a return on an investment. Sometimes you have to take a loss, depending on the market. You can't fight with the supply and demand principle. I do believe if you put it for sale on an auction site, such as eBay, you're bound to find someone who'll make you a solid offer. I don't necessarily think a forum is the best place to field offers, but it might contain the niche market you're looking for (I assume that's why you posted this). Either way, throw that baby up for auction; couldn't hurt.
