What's new
For a third sound channel.

LA47536 supports up to four.
That's unusual. A bass channel, maybe?
So, I'd gather it's supplied by the regular JVS power connector (the 8-pin JST one) and the amplified audio is out on CN1?
 
Correct.

Although don't assume the power connector follows the JVS standard.

Thank you for this. J106 is used for PB1 but not PB2. It splkts and feeds to the v147 POSITION PCB that attaches to the PB1 game board at J4 and J1

I was able to locate a site selling these molex connectors as well. I love this game and wanted to put this here for reference. There are cheaper comnectors available on te.com but these connectors seem to be easier to assemble as they will hinge open.


These parts can all be found on te.com

For J107 its a 2x10 2.54mm pitch connector.
I used a 2x12and it fills the gaps on the sides to let me use the snap connector.

Not an IO board but this looks like a good place to ask what a Video Mini board would have been used for. I’m curious as the Cyberlead has a seemingly unused 10 pin output on its IO labelled V Mini.

I'm trying to make sense of it looking at the manual. I'm not positive but I wonder if this is just a test pcb, like Dottori-kun.

Interesting and sounds very plausible - for various stages of the assembly process perhaps. The cable from that V Mini output is still in my Cyberlead and I had it plugged incorrectly into the JVS Jamma adaptor kick harness output. I’m considering cutting the cable in half and terminating the cut ends with CPS 1/2 kick harnesses connectors - but didn’t want to if it could be important one day.
 
Okay I think I found it in the manual. You can see the little V MINI board here. In the text it says to remove the five connectors and the board and replace with a JVS PCB and only plug in the FLIR connectors but not the J79 EL connector. So the machines shipped with this board.

I now have a namco V342 signal amplifier board. Can anyone tell me its detailed functions?
I have connected the drum to the black socket on the left, and I connected the V329 IO board to the 10-pin white socket on the right. How should I connect it?

I have bought a namco 256 with time crisis4, and io and light eyes. Anyone know how to hook eye to this io ????

Thanks for this.

Like you said, there's not much information about this filter board. The manuals I've seen online don't appear to match what the silkscreen on the pcb of the filter board.

Do you happen to know what J104 is for? On my cabinet it's wired up to a 2 way connector and the wiring is violet and white. Your reference pic doesn't appear to have the connector for it, but mine appear to go up to the speaker section. I'll eventually do a trace of it. The PCB cage I have is for Point Blank 2.

I think the wiring diagram is at the end of the manual https://archive.org/details/pointblank2

Unfortunately that's the manual I've been reading that doesn't match any of my markings on the pcb. J104 for example is not listed in that schematic.

Not sure if the Japanese cab is slightly wired different to what looks like a UK cab but there's definitely discrepancies.

I’ll check my board later today to see what it has connected to it, my guess is that it’s another way to connect the 24v for the solenoids to the guns
 
Definitely not the solenoids.

As @Srayer posted in his pics, the filter board on mine looks like this - the same as his except J104 has a connector.

J108 deals with the input power from the PSU's and J105 deals with the guns

J104 is nowhere to be seen on that schematic. Heck even J108, J107 and J105 can't be found. I'm assuming J31 on the schematic is J107, J16 on schematic is J105 and J15 on schematic is J108.

I'll just have to strip the cab out and try and trace where the wires go.

No, I don’t know, unfortunately. There’s generally not much up in the speaker section, so I’d think it’d have to be either the R speaker or power for the marquee light. Looking at the parts side on my board, I see the two pins for that connector go to an empty spot for a relay (RL1) and diode (D1), with a trace leading to a empty spot for a filter (FL1). From there, the trace goes underneath the 48 pin edge connector (kick harness), and I can’t see where it goes from there. I’m guessing that on your board, all those spots are filled with components.

Given there’s a relay, it’s not a speaker connector, so probably lighting related. But I don’t know why there’s a relay. Is there a light in the marquee area that can flash on and off?
 
Also, could you snap a picture of the other side of the board? I’m curious to see the components that make up that full circuit.

I think you're right. I have this on my marquee, but it doesn't seem to do anything when I play - not sure if it's working or not tbh

Here's the best I can do for now

No, that pic’s great. It has the relay and diode just like I would have expected. I pulled out my multimeter and found that trace that goes under the 48 pin connector is connected to pin 7, for what it’s worth. But, I haven’t found a pinout for that connector.

I can’t really make out what those two boards are in the marquee area. I’d be curious to see the other side of them if you ever have time to snap a pic. Or maybe someone else who ones one of those cabinets knows. Mine is just a conversion; I’m very jealous of your dedicated cab 😁

Edit: I’ve been dying to figure out this mystery, and have been scouring the Internet for clues. I’ve found that pin 7 on the 48 pin connector is “GOUT4”. There is also GOUT0-3 on pins 3-6, which are routed to J106, which @ignignot said above is used for Point Blank 1. I’ve also found that PB1 has a “GOUT” test mode, where along with the gun tests, there’s a “Flash” option that the USA manuals say is not used. My USA PB2 does not have this option, and it’s not mentioned in the manual.

My speculation here is that enabling “Flash” on PB1 with a filter board like yours will cause the marquee to flash whenever a gun is fired. Presumably those two boards in your marquee area are some kind of lighting that are controlled by that relay circuit. But this is all just a guess.

If you’re curious, you could manually trigger or bypass the relay, and see what happens to those two boards behind your marquee.
