I built a multi jamma MK machine last year with all MKs in it. Everything was fine until I moved and thought I was very gentle with the cabs I have. All the other MK boards I have work fine just like they did before the move. Unfortunately though MK 1 has some visual issues now. The rom check...

You need to ground the only green wire with any black wire. Then I would plug just the Ps into the wall and turn it on with nothing attached to test it. I just recently finished my multijamma and this is the same thing that held me up, took me 3 PSs and 3 weeks to firgure it out because noone...

what size locks do I need for a mk2 dedicated machine? I noticed on happ's website there were a bunch of different lengths. Also I heard you can get the same locks at home depot but I couldn't find them there, can anyone confirm this? thanks guys.

I bought a multijamma to use with my mk boards and upon arrival I can't get anything to work. I bought a power supply from newegg.com to power all my boards and while I was waiting for it I took an older one and tried using it for just 2 boards to see if the thing works. I get a green light on...

let me see if i got this right. I would need to take the wiring from the CP and multiply it and run it to resistors for each boards button then from there to the buffers then to each boards pin out? i am ok with soldering I can do simple stuff.

If you have the sound board you can connect it using an pc IDE cable. The hardest part is making sure the pins match when you connnect it.

im sorry im still a little lost as far as resistors and buffers go. I need 4 buttons added to the board low punch and low kick for both players. bare with me in new to this and didnt even know really that all the press went through a chip and what not. Just assumed they just worked

hey thanks for confusing me! can you maybe explain it so a newbie in the arcade can understand

Is there an expensive way? at this point I have to much money in this to just hack something to work. I appreciate the idea though.

any fix for this? also I found it works fine with mk1 and mk2 hooked up but as soon as i introduce a game with the added run button all hell breaks loose.

Thanks for props on the idea. I currently live in an apartment and I plan on buying a house within the next 6 months so I wanted to be bale to make the cabinet as easy to move as possible and since it's not so easy to just go to the store and pick up new MK boards I wanted to be able to remove...

I am building a jamma cabinet with mk1 through mk4 in it. everything is going smooth thus far but now I have an issue when trying to wire in all the boards. I can wire mk2-4 into my custom box and they work flawless. When I hook up mk1 it goes wacko. any of the low buttons when pressed activate...

That 4 pin one looks like it will work perfect for the volume pot for the sound board but what about the control points those all look to big for the tiny pins. I also just wanted to say I appreciate all the help guys.

My local radio shack had nothing of the sort that would fit it. The guy tried showing me serial connectors. I rummaged through their parts for like 15 minutes and couldn't find anything. Also that site is a little confusing any idea which part numbers I will need from there? If not I'm gonna...

where can I buy connectors for the controls connectors and power connectors for off board sound? I'm not looking for premade wires but just the connectors. Or the info on size and spacing for the pins.
