I've already made a 16F84 Simon.  Check out:

If it helps, great.  If not, and you still want the toy, just build up the
circuit :)  I'm sure I'm doing it quite differently, though, so it may not
solve your problem, as I'm doing asynchronous tone generation relative to
the user inputs.

One item to note is that I say you can use a 6V "N" size battery (which I
do).  There has been much discussion on this list concerning the fact that
6V is over spec for this chip.  You may want to run 4.8V if not use a 5V
regulator with a 9V battery.  Hasn't caused a problem for me, yet, but it's
worth noting.
