Question about Apple2 King's Quest2

[johnkun]

Hello!
I am playing King's Quest2(Apple2 version).
And I unlocked and opened the third door.
Now I have a trouble.
This is because the message"Please insert disk 3 (front)" is displayed!!
But I have not disk3, that is to say,disk e.
I have only disk 1(disk a and b), disk2(disk c and d) and save disk.
Why is this?
Why is this message displayed?

I have searched for the disk3 on the internet.
But I can't find it.
I always found only disk 1(disk a and b), disk2(disk c and d) and save disk.

I think that there is no disk3 on the King's Quest2(Apple2 version).
Is this my idea true?
Is there the disk3 on the King's Quest2(Apple2 version) on the earth?
Does it exist on the earth?

And I think that it is because there is a protect on the King's Quest2(Apple2 version).
Is this my idea true?

Please help me!!
Please give me an advice.

I cleared the King's Quest2(the latest version).
This is very great!!
Now I want resque the woman on the King's Quest2(Apple2 version)!!
Please help me!!

Sorry, but we don't support anything other than the software we actually developed. You might ask at the Sierra forums though.

Or possibly someplace that deals with the older versions. Like http://www.sierraplanet.com/
