                        SON SON - By Capcom

This is a very good but little known game from Capcom around 1984. It is a
forced horizontally scrolling game. You have control over 'Son Son' or
'Ton Ton' - two little characters that can move up and down the scrolling
ledges attacking the baddies. The scrolling is very slightly hesitant.

There was a sequel that appeared on the PC Engine but I don't know if this was
a coin-op or not.

The board is a Capcom original with the serial No. 07137

There are two boards connected via an edge connector as follows:

Top board ( CPU ):

--------------------------------------
E                                     
D                                     
G                                     
E      SS.03E
       SS.02E
C      SS.01E
O                        SS3.V12
N                                     
                                      
--------------------------------------

                                      
Lower Board


--------------------------------------

         SS7.V12
         SS8.V12           SS5.V12
         SS9.V12           SS6.V12



--------------------------------------

The markings are those that appear on the eproms themselves.

The main processor is a 6809P.

There are two AY-3-8910 and what appears to be a YM2203 covered by a sticker
bearing the serial No. 07137 ( that I didn't want to remove ).

The crystal is 12 MHZ.
