- I have heard that one way to do it is to write part of your code to a portion
- of the master disk that is not normally used by the operating system you are
- running on.
-
- Some disks for the Apple II series used a system that wrote the tracks in
- a spiral pattern, completely different form the standard Apple II DOS.
-
- However, be sure you want to do this, when I owned an Apple II I wouldn't buy
- anysoftware that I couldn't make backup copies of. If The master disk
- gets trashed and I need to get to a file, what am I supposed to do?
