Hi folks,
Does anyone have the pinout for this ? It's labeled 'V187 ASCA-2B PCB'. To my knowledge, this filterboard was used for Rapid-River and Final Furlong. There are 5 connectors on this board, marked J203(9pins),J204(15pins),J205(6pins),J206(12pins),J207(12pins). Can anyone with a working Rapid-River tell me how to wire this ? Thanks.
 
It looks very thorough to me. Are you saying that there is an extra board that is not covered in this manual?

What I would like to see is a diagram that shows the filterboard (V187 ASCA-2B as there also exists an ASCA-2A board with another 8pin (power?) connector). I don't see an exact match to the J203-J207 connectors on any page either. Do you ?
 
I don't see a dedicated filter board, and the drawing I am looking at doesn't list the part numbers you are referring to. I do know that filterboards generally do not change anything. Signals go in, are filtered, and then leave the board, usually in the same order they entered. In fact, it is very common to just remove filter boards.

BTW, the power diagram I am looking at is the last two pages of the doc linked above.

Yes, I started with these two pages. but there are not all connectors shown (by counting them) and there are duplicates (in number of pins). I traced on the board to find out which pins are GND to understand which 12pins belong to which of the 12pin-connector on the board. I just wanted to make sure my wiring is correct before powering it up - I would miss this game ;-)

The question is merely - the J104 connector on the other (V187 ASCA-2A) board seems to be an 8-pin power-connector with +12v, +5V, +3.3V (top row) and 4 GND's (bottom row). It would be good to know if that connector matches the 8pin Capcom I/O power-connector or not. In the badest case I would connect 12V to the 3.3V. If there would be some parts on the board, I could more easier identify the power's by going thru their datasheets.
