Curious about how many have been sold, is the serial number simple the production number?
Also, maybe the quality of the joystick (which many seem to have a problem with) has anything to do with when it was produced.
Please post your number, location of purchase, and if you have any problems. Also, if you got yours in a press kit please state this too.
Lowest (press kit) = Perifractic has #00000007
Highest (press kit) = GenXGrownup has #00000103
Lowest (bought in US) = WozNYC: #00000508
Highest (bought in France) = D Leroy #00019213
