Harem by I.G.R 1983 hw informations

Finally,i've found this rare and "obscure" pcb.This document is only for hardware info,no dump (that it's verified good).
-About encryption,this game uses a PAL16R4 for key.Hw connection schematics are in attachment.They are hand-made since i haven't manuals of pcb.
-About sound,since upper snd-i/o pcb is almost identical to Scorpion* (look attachments again) it uses the Digitalker Speech Chip (it has ID code erased) and its eprom is the a1_ic25 (that on my pcb is marked H1+H2).
-About dip-switches,by direct test they are:

SW 1   2
   OFF OFF 2 lives
   ON  OFF 4 lives
   OFF ON  3 lives
   ON  ON  255 lives (test)
SW 3   4
   OFF OFF 2 coin 1 play
   ON  OFF 1 coin 2 play
   OFF ON  1 coin 1 play
   ON  ON  1 coin 3 play
SW 5
   OFF normal difficulty
   ON  hard   difficulty (when you carry odalisque the weight of her slow down you,and to put her on bed you must press attack button.It's not done automatically as normal rank)
SW 6   7
   OFF OFF 500 time-bonus pts (for each odalisque,not for stage)
   ON  OFF 850
   OFF ON  1150
   ON  ON  1350
SW 8
   OFF not used
Bonus life is fixed to 20000 pts only.

*NOTE The fact that Scorpion pcb is marked I.G.R. (on stickers too) confirms that I.G.R. was the developer of Scorpion for Zaccaria.So,Scorpion was another of 3 games produced by I.G.R.
