I assume it is done "in the spirit of Woz" and a microcontroller
would be overkill (if I judge its functions right).

Steven Weyhrich has a section about it on his Apple II History
website:
http://apple2history.org/history/ah09.html

And there is also a rather recent albeit short discussion here:

Maybe contacting David Craig for the engineering specification would
be a good idea...
