I had to write all of our product manuals at my first engineering job using XyWrite, which did not have auto-save. After losing a few pages due to a power failure and not having saved often enough, the owner of the small company put a timer on my desk set to 10 minutes. When it went off, I had to save to disk (3.5" floppy, IIRC!) and reset the timer. I hated that thing!
