As well as a real "APPLE ][", we had a clone which displayed "GALAGA" on boot, bought from Singapore I think. It was otherwise identical to the real one, including the rest of the EPROM image. So there really were clones "Stolen from Apple".

To get it to run ProDOS we had to reburn the EPROM on that sucker :-): http://en.wikipedia.org/wiki/Apple_ProDOS#Unlicensed_Apple_I...

There's a similar mechanism in OSX to this day: http://www.projectosx.com/forum/index.php?showtopic=1320
