I’ll never forget the book. […] The book was a huge compilation of all around interesting stuff. Weird Apple II tricks that were pointless, but endlessly fascinating. Like the fact that there were extra offscreen pixels of lo-res graphics memory that you could write to, that never got displayed. Or how to put “impossible” inverted or flashing characters into your disk directory listing. Or how to modify system error messages. Not very useful, but really fun to know and really, really cool to mess with. My dad was convinced I was going to somehow break the computer with all this hacking, but a simple reboot always fixed everything.
