Capcom CPS 1.5 Boards

[Bar81]

Can a Capcom CPS 1.5 board like The Punisher or Cadillacs and Dinasours work properly with Q Sound output if it *doesn't* have the case and the PCB that connects the video and audio boards like on the left in this picture:



Thanks for any help with this.

Maybe I'm misunderstanding, but how could that even possibly work?

I don't know. A seller is claiming that there is a jumper that can make it work so that you only have to connect to the JAMMA connector on the bottom video board. But if that was the case, then why would Capcom waste its time making the board joining the audio and the video? My knowledge is limited in this area so I'm hoping an expert can shed light on this.

Sounds like the guy may be trying to push a bootleg.

Thanks. Something just doesn't smell right.

Well, you can certainly get mono audio off the JAMMA connector, and yes it's probably selectable via a jumper.

CPS2 boards have this in their soft-DIP settings, and MVS boards have a dedicated switch.

So no Q Sound. I figured. Thanks.

No you can't. Without the front board the Q-sound board wouldn't get +12V hence the amplifier wouldn't work at all. And the mono traces wouldn't make it to the A-board anyway.

Too much trouble. I'll look elsewhere. Thanks all.

Hmm ok, I was just basing this off of my experience with CPS2, but sounds like the 1.5 is quite a bit different.

Just FYI - yes this can be done with a couple of wire hacks.

Thanks, no Q sound through JAMMA though as I figured.

Correct, but you need a stereo amplifier to use the Q-Sound anyway, and that always runs through the two RCA plugs which you can plug directly into on a wire hacked board.

You see a lot of caseless ones, I never worked out where they all went. Presumably they die, operators open them up, chuck it on the shelf and eventually throw the case away.

Oh. So even with the PCB connecting the boards together its still mono. Thanks again.

What I have noticed, is there's wrongly (IMO) only a modest price difference between cased and uncased, so to be honest I'd hold out for a cased one.

Thanks, I found a cased one even cheaper than the uncased one.

Just to add a bit more information, the middle board needs to be powered for the game to boot. And both boards need to be either desuicided or alive.

Here is the pinout for the connectors, I had to build a custom one for a friend who got one without it:
