What kind of logical advice are you looking for? A500's are a very common machine that can be found in bulk on ebay... they are not worth much money wise. As Toni said, there are other A500's with the serial number 1. Maybe it was part of batch 1 or some kind of printing error at the factory?
Anyway what colour is the power LED and does it dim or turn completely off when running games? This will give you a clue on the motherboard revision. If the power LED is green then there is no way it will be the first ever A500. Hope this info helps
