-Programming
------------
-
-I went to [Rochester Institute of Technology](http://rit.edu/) for a degree in
-Computer Science.
-
-I've done a lot of different things in the field so far. Right now the things
-that are captivating me are artificial intelligence and clean, simple,
-*useful* web applications.
-
-I find programming beautiful. That might sound strange, but there are aspects
-of programming and math that I can't describe any other way.
-
-You can take a look at my [projects][] to see some of the major stuff I've
-worked on, or cut to the chase and look at [my BitBucket account][BitBucket].

-
-Photography
-----------
-
-I like photographing people. Other things as well, but especially people.
-I tend to gravitate toward the "art" aspects of photography more than the
-"journalism" aspects, but I can appreciate both.
-
-I shoot digital and film (35mm and medium format) depending on my time limits
-and mood. I develop film in my bathroom and print it in a rented darkroom.
-When I print digital I use a lab nearby; I don't have the money for a
-professional printer just yet.
-
-Dancing
--------
-
-I teach blues dancing here in Rochester as part of [Lady Luck Blues][].
-I started blues dancing a few years ago and haven't stopped since. My favorite
-aspect of dancing is connection and blues seems to bring that out more than any
-other dance.
-
-I've also been swing dancing for about seven years. My first love is Lindy Hop; I
-go to classes, workshops and exchanges as often as my schedule and budget will
-allow.
-
-Lately I've begun getting my feet wet in tango. Whether it'll ever become as
-important to me as blues or Lindy remains to be seen.
-
-[Lady Luck Blues]: http://ladyluckblues.com/
-
-Music
------
-
-I play electric and upright bass. I've played in a metal band in the past, but
-right now my focus is on jazz and blues.
-
-I DJ at swing and blues dances fairly often. My taste is pretty broad, and
-I'll cater to whatever the floor wants, but I tend to personally enjoy
-slightly down-tempo, small-group music. Let me know if you need a DJ for a
-dance.
-
-About the Site
------------
-
-If you want to know more about my site you should check out the [blog
-post][hyderewrite] about how I rewrote it.

+
+Our [CHIP-8][] emulator in Common Lisp is coming along nicely.  It can play
+games, and in the last post we added a disassembler so we can dump the code of
+ROMs.
+
+In this post we'll add some low-level debugging infrastructure so we can set
+breakpoints and step through code.
+
+The full series of posts so far:
+
+1. [CHIP-8 in Common Lisp: The CPU](http://stevelosh.com/blog/2016/12/chip8-cpu/)
+2. [CHIP-8 in Common Lisp: Graphics](http://stevelosh.com/blog/2016/12/chip8-graphics/)

+4. [CHIP-8 in Common Lisp: Sound](http://stevelosh.com/blog/2016/12/chip8-sound/)

+The full emulator source is on [BitBucket][] and [GitHub][].

 We could have used a lock from bordeaux threads to manage this portably (though
 more slowly), but I wanted to play around with SBCL's concurrency stuff.
 
-Finally we just need to start up the timer thread:
-
-```lisp
-(defun run (rom-filename)
-  (let ((chip (make-chip)))
-    (setf *c* chip)
-    (load-rom chip rom-filename)
