Apple Pascal

I am interested in learning more about Apple's Pascal operating system. Is it software that needs to be loaded from disk or on a card that needs to be installed or what?

Apple's Pascal operating system is a version of the UCSD Pascal system, written at the University of California at Sari Diego. It is supplied on disk and loaded into RAM, where it is used in place of the normal Applesoft ROM. This disk is all that is needed on newer Apples (IIe's and IIc's). Apple II's and II+'s don't contain the extra RAM needed to hold Pascal and require the Apple Language Card—a special 16K memory card which plugs into interface slot zero.
