There's a reverse-engineered partial circuit on VOGONS:

I *may* have the little chart that came with one of these, but to be
honest, I've never used the chart. My approach is very simple.
* Remove all of the jumpers.
* With the switch in the "normal" position, move a single jumper
around and note which segment is illuminated.
* Repeat with the switch in "turbo" mode.
* Create your own legends.
Like other posters, my legends usually say "Lo" and "HI". But you
can get creative with yours...
