Anyone use CPSII?

I'm curious. Can someone please give me a basic rundown of how this works? It sounds similar to the Neo Geo. You have a basic "A" board, and then "B" board games? It's still Jamma compatible, right? What about the 2 extra buttons? How does this work? Just spill everything you know! Thanks!

There are A boards and B boards, the B board is kind of like a cartridge that you attach to the A board. The A board is connected to the jamma harness via a straight jamma pinout edge conector. That means that it is mono and "three" buttons. The extra three buttons, or third and fourth player buttons are connected via an extra connector. There is also line level stereo output via RCA connectors that needs to be run through an AMP of some sorts. If your planning on using this through a supergun you just hook the sound up directly to your stereo or supergun though.

The D&Ds have the 4th button on the jamma connector.

In my opinion I like the CPSII board set-up in general.

I like the fact that the pcb parts are in protective plastic shells and that the mother board has it's own cooling fan..

This system has become my new thing this year,besides STV and MVS etc..

I've bought 7 games already and I'm going to send all the chips to Razoola for the fix..

I don't care what the game is worth I just want them to work forever thus getting each game fixed....I like the games so I want to preserve whatever it is in them I collect.

When I first hooked this up in the Candy I didn't realize it doesn't need the -5v line that some Jamma boards need though I have that -5v line set up so I can connect or disconnect it with a plug.

I bought one of the CPS 2 3RD AND 4TH + KICK BUTTON HARNESS that are sold on Ebay for $10.00
When it gets here I'm going to wire it into the Candy cabs buttons..then put one in the Tekken 3 machine.

The only thing that I haven't really figured on is where to put all these big boards..
Having a collection of these can really take up some room,but much easier to me then storing/collecting Jamma pcb boards.
(I put the PCB boards I buy/collect in Priority mail Boxes.)

I'd like to see how people store the CPSII boards..
What do they do pile them 10 high..?

Pins 07 to 28 can be configurable to anything as games require. This includes coin inputs, coin lockouts, joysticks and buttons.

On the JAMMA connector H / 07 is the Key Pin which stops the connector being joined the wrong way around. NC = Not Connected.

Awsome Bro..Thank you..

Hehe.
It's good that CPS2 has its own cooling fan.
But DAMN, is it noisy. What a whiny noisy fan it is.

Hell yeah man :\

I wonder if there's a trick to quiet it down a little, or replace it with a model of equal shape and size and less noise

slap a 100 ohm resistor on the power wire to the fan, and it'll be nicely quiet without overheating.
