Ok, I'll start by making a list of the sections and how well I understand them.
Maybe we can fill in the blanks then. I figure any annotation is better than
none :)

The divide by 3 is really neat. I haven't looked at the playfield registers yet.
I'm still trying to grok the horizontal position register section. I know what it
does, but I can't quite see how yet. :) I really want to know if you can do any
other stars-like effects by "misusing" that section.
The sync counter is became easy to understand, once I realized that the lsb
is on the left, and the numbers in parens on the compare lines are octal.
That took me a while to figure out, so I think putting little things like that in
the guide would be a good idea.

Good question. Well, so far all I've done is the divide-by-3 circuit, which doesn't have the transistors.
I'll see what it can do with the FET's next. I may have to use latches or just
an equivalent circuit for the block in question.

Well, if I wasn't becoming a daddy in 4 short weeks, I would...but I think I'd
better choose my projects carefully in the short term. :) I'm just getting
prepared for when I do have the time.
It looks like Chris Wilkson is doing an even harder job...I just found this link:

Look at his entry about halfway down the page.
