I have an Area 51/Maximum Force board that has a bad RAM chip so I transplanted the EPROMs to a Maximum Force board. Now the game is throwing me a Ream Error. I looked it up and it has to do with the Security chip. So I am wondering where it is so I can transplant that chip too to the new board.

I'm assuming you are talking about Street Fighter II Champion Edition since those commonly came in Zback cabinets.
Street Fighter games are typically it's laid out like this, with top row buttons 1,2,3 coming from the jamma harness, and the bottom row is laid out with buttons 4,5,6 these are usually coming from a kick harness, occasionally button 4 also comes out of the jamma harness instead of the kick harness, but the control panel layout is still the same.

Hope that helps you.

Yes this helps me alot. This will help me wire the buttons up to the harness when I get the stuff to go into the cab. I am rewiring it from a light gun game to a fighting game. So the CP has only the player one and two start buttons(that I will be replacing with new ones.) Am thinking about making it a street fighter game if I can find a cheap board for it.

I am wondering if anyone knows the button placement for the Zback cab? As in what buttons are 1 - 6. I need to know for wiring purpasis as I am converting my Zback cab back into a fighting game from a light gun game.

I wish I could get one of the area 51s if they are in an origanle cab.

I watch it on my computer that's hooked to a 55" TV with 5.1 sound

Nintendo Vs Red Tent

I wish you luck in fixing it up. I would love to have a Nintendo cabinet my self and I so want the Nintendo Vs Red Tent.

I'm wondering if the PCBs out there share any common RAM chips? This board I have some of the RAM chips have some rust on them and will most likly need to replace them so I am hoping that a lot of the PCBs share the same type of RAM chips so I can order them in bulk if I have to.

I just won my self a Centapid PCB and now I am thinking of making a set up for testing out PCBs. I am wanting it to be able to test alot of type of boards so wondering if it should have a JAMMA connecter with mutable converter bords or just splice in each edge connecter into the wiring harness.

hey I was wondering if any of you live in the Portland, OR area because was thinking of maybe meeting some of you arcade collectors to talk to and have some fun. As I am trying to start my own collection too.

well for me eather is good. Cheap CRTs are hard around here. I can easly go to goodwill and get a LCD cheaply. I would love to have it more origale if I could find cheap CRTs but I dunno if its possible here.

I am wondering how you all feel about using a LCD Screen in an Arcade machine because I am thinking about building a few machines from scratch and want to use an LCD screen.

the mortal combate one looks good to me.

the 1998 Godzilla Pinball.
