[Tron] Did the ISOs exist in the original film or was that fabricated for Tron Legacy? And how did Quorra go to the real world?

It's stated in Legacy that the ISOs appeared after the original movie. They might have existed prior be they were not known to Flinn. Quorra got to the real world the same way a human would. The machine that Derezzes basically built her a body in the real world.
