Hi all,
I've just bought an st-v board with a plugged daughter-board labeled "sega 1996 video bd for st-v".
I cannot find any information about this board around the internet (even on system16 site), so I hope someone here could help me.
The board fits all of the four expansion connectors and it has on the left side (between CN3 and CN5 connectors) 2 s-vhs plugs and 3 RCA yellow plugs. (If it helps I can send a picture)
What this daughter-board is supposed to do? Does exists a service manual around?

Thank you in advance

Thank you for the answer.
Unfortunately I've bought the st-v with no cartridge, so I can't tell if it was supposed to be used by a game or some kind of application.
Anyhow the only relevant things I can tell are:
0) This daughter board is an original Sega board.
1) The main board dip shitches have the following configuration:
JP4 = 3-2
JP3 = 3-2
JP2 = 2-1
JP1 = 3-2
which is quite unusual according to the st-v service manual.
2) Once plugged in a cabinet, the board complain for a missing cartridge (I've no games at the moment to play with) and there is no extra test menu entry in service mode (i.e. st-v standard japanese bios, so it is meant to be used by some kind of game/application)

I'm sorry, but I'm not able at this time to tell where this board originally cames from. I'm investigating about it.

Thank you again for your help.

Take a photo of it and either send it to me or post it on a website, then I can have a look and show it around to a few people.

This is the hardware country setting I think now your board is hardware setting for USA (i need to check).
just like the saturn bios can be JP/USA/EURO and the board can be set to different region. some game will check bios region, other (sfish2 on stv side) will check board region.

That board came from a photo machine, the input is from a camera and the output goes to a priner, like snk neoprint that use a mod neogeo board.

Thank you for the answer.

Interesting... the bios seems to be a japan bios because it says at boot time it is intended to be used in japan only.
So I deduce the jumpers has been changed to USA region in order to make such a game which checks the board region to works, while keeping the japan bios.
If I understand correctly, I may then reset the jumpers to the configuration described by the service manual. May I?
Can you please tell me the other jumpers setting meanings?

Furthermore, I understand sfish and sfish2 are cd-rom based games, so they require a cd-rom controller board.
If this video board has been intended to be used with one of those two games, there is a thing it is not clear to me:
According to the layout of this video board and according to the cd-rom controller picture I could see from system16.com, these two boards are not supposed to be used together in a tower configuration because they does not provide any CN type connectors on the component side, so they are mutual exclusive.
This makes me puzzled on the kind of game this board has been designed for.

Thank you.

I know only setting for japan and export.
You can set the jumper as described by the service manual with no problem.
But You can't remove the second board it has something like a bus terminator on it; standard stv board have a dummy connector pluggend in.

Yes you can have cdrom inerface OR video in/out inerface not both at the same time.

It's designed for game like this:
