hmm....I had a commodore vic 20..amoung other computers like radio shack computer....
I think they run it off of a network of Apple II computers. A Fiber optic network of say 100, probably 1000 Apple II computers. That is why they have to shut it down every nite, to give the floppy drives a break.
I envision a guy running around putting in floppies(which back in the '80 were really, "floppy," and hard to put in)
