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.

The x86 protection model is notoriously complex, with four privilege rings, segmentation, paging, call gates, task switches, and virtual 8086 mode. What's interesting from a hardware perspective is how the 386 manages this complexity on a 275,000-transistor budget. The 386 employs a variety of techniques to implement protection: a dedicated PLA for protection checking, a hardware state machine for page table walks, segment and paging caches, and microcode for everything else.
