SN10207 has recently surfaced, belonging to its current owner Pete the Plumber for the past 25 years.
The game has been stored in the basement all this time and although not currently functional, Pete says it is in good shape. Apparently one of the fuses on the back door area is missing. The owner reports he even tried calling Nolan Bushnell himself but Nolan's assistant would not patch him through on the phone.
