Hi,
 I think I remmeber that an original Gorgon disk would not work, but
the cracked copy would. Also the Ortho disk would not boot on the IIgs.
  Also as  it was mentioned here already that if you did not have a
disk controler card for the older style 5.25 floppy drives in the IIgs,
like the Disk][ you would have problems. This might have been spelled
out in computist.
