Apple IIGS and Integer BASIC



I am trying to run old Apple II programs written in Integer BASIC on an
Apple IIGS (original Woz version with 256K of RAM). I can list the programs
with the CAT command, but can't run them.

The Apple IIGS can run Integer BASIC programs, but only under DOS 3.3, not
under ProDOS. ProDOS is not compatible with Integer BASIC (though it is
compatible with Applesoft BASIC).

To run your programs, first start up from a known-good DOS 3.3 System
Master (or other DOS 3.3 startup disk that loads Integer BASIC in RAM).
