I Pulled The Computer Off The Truck, But I Can't Find A Number Of Any Kind On It At All. The Large Plug in Has 14 Prongs And The Small Plug in Has 10 Prongs. Can You Tell Anything By This ? I Can See Down Inside The Part That Connects To The Air Line And It Has A Little Round Cap Type Thing In There That Has A Number 5206377 RCA CA 8714 And This Is The Only Number I Can Find.
