The unit works fine, but it has not been serviced and appears to be original as best as I can tell. I'm no electronics expert though. Such a really cool find in this good of condition. The unit may show slight signs of cosmetic, wear, consistent with its age, but is otherwise in excellent shape. USPS shipping. The rate is calculated using the product weight and dimensions.
