klov was nice enough to link to the manual... it shows what chips are what in there around pages 12-15 aqnd a little later explains self test etc. Best of luck.

edit, hmm i cant find it either. WHy the eff did they only show a partial of what is where? mabye if you look at the pcbs hopefully they silkscreened it so you can see where these chips are.
