This game was originally distributed on two sides of a floppy disk.
However, none of the previous deprotected versions included the second side, which contains the ending sequence.
This is the only version that has that ending sequence.
To preserve the aesthetics of the original, it retains the text that prompts to turn over the disk.
There is no need to do anything with the disk, just press a key to continue at the prompt.
