SN10439 currently stars on The Electric Playground TV show. http://www.elecplay.com No idea of its history but it seems to be running well and the person on the show who sent me the serial number says it eats his quarters regularly so obviously it still gets a lot of plays.

When the new season of Electric Playground began, the original set of machines that 10439 stood with (which included a Nintendo Virtual Boy and a Vectrex console) were removed and it looked as though 10439 would no longer appear on the show. However in recent episodes, the blue machine has been occasionally glimpsed as the camera pans across to the hosts so it has made a comeback! Many thanks to the people at Electric Playground for continuing 10439's starring role!

SN10439 was recently showcased on The Electric Playground www.elecplay.com in a story they did about the formation of Atari. Click the thumbnail for the one-minute video.
