hey guys
I decided to build a supergun i had few jamma boards laying around
& i no longer got a cabinet to play them
& since where i live all the collectors are ''mainly $$$ eating crooks''
I decided to build a supergun until i find a decent price cabinet
What i got
ATX POWER SUPPLY
JAMMA HARNESS
JAMMA PCB
Control panel
RGB TO TV ADAPTER
Now my main question is
should i use a Arcade power supply.....?
& if i do so do i need to put a Iso transformer? or something... will it be live with current?
i never really played with them before.....
am i better to stick with a ATX?
and if yes how can i connect it to the jamma?
thanks!!! alot!

ATX power supply can be used as long as the power good signal is provided to the main connector. An arcade switching supply is easier to wire to because it has terminals. I has a bit less power but is well suited for jamma boards. No iso transformer is required unless you are connecting to an arcade monitor that needs an iso trans. Since you have an rgb to tv adapter this you do not need an iso transformer.
Both the ATX ps and the arcade switching supply use regular line voltage.
Here is a link to wire up an ATX supply as a stand alone bench ps (same as for arcade games).

so your Telling me
I should use a Arcade power supply bottom line :P
but i need to hack a power cord to put in the 2 AC screws in the arcade power supply....
but my scare was if i do that that the box becomes with 120V inside & when i toutch it it will pass my body.... but that is not the case...? right
I have one of these already hacked with 2 wires.. to put in the AC/AC spot...
but Do i need to Wire the middle one To ground on the power supply???

The 3rd pin goes to the FG terminal (frame ground) of the arcade power supply. If it is properly attached to a ground plug there is no danger of getting a shock from the case of the power supply. You will get a nasty shock if you touch one of the open ac terminals on the end of the PS. You can cover these with electrical tape or a piece of plexi if you want additional safely.
I used an arcade PS in a test box that I built. (supergun). It is totally enclosed so there is no danger of shock even though the space is very confined.
See picture that shows AC terminals and FG terminal (Bottom 3)

Sweet thanks ! i could use my pc power supply to case it like you did ..!
since i won't be needing it & some pin is broken on it....
>by the way
My other concern now is about the ''controller''
the jamma harness has to go Up to the controller aswell that makes a bit of a hassle to drag.....''
since im gonna use only a normal CP from an older cabinet i had...
How should i put it the ''best way''
Let me know thanks!

I made the Jamma board part of the supergun just long enough to plug in a jamma board. The video and the p1 and p2 controls are routed inside the box to DB15 connectors. I used DB15 because you can get cheap game console cables that plug into them for a few dollars at a surplus store. The video connector is female and the P1 and p2 connectors are male. This prevents a connector from being put in the wrong place.

amazing work!!!
now i need to find a enclosure for my supergun... since my psu is a ATX CASE the arcade supply wouldn't fit in....
About the female controller connectors
do you have the ''schema wich to connect to wich???''
also the Schema for the connection made on your Sticks
so i can know How to correctly make them :):)
thanks!!:!)

Here is a link to an old site that has alot of supergun info.

I'l be keeping an eye on this thread as that is to be my next project, but I realy want to finish outrun completely first. Any best practice you could share with us BobA?
Regards.

I would say that the most daunting task in building a supergun is taking care of the extra 3 buttons for fighting games. If I were to build another I would include terminals for --BINGO! Either that, or I was attempting to say "before" but it was too many letters to type--,B5,B6 and ground on the supergun for player 1 and 2. This way the extra kick harnesses could be tied into the supergun with minimal work. Superguns seem to be built by alot of people who want fighting games and this would accomodate the extra buttons that the Jamma harness does not. -5V should also be wired to the jamma harness as it is required for some games and will not bother games that do not require it. A PS that provides a visual indication of the 5V would also be helpful since the 5V must be adjusted for some games. This can be provided on the arcade PS or test points can be added to tie in a DVM.
It is hard to draw the line between a supergun and a fully optioned jamma test fixture so the meter is probably not required for most fan type superguns.
The addition of a RGB to NTSC or PAL converter is critical for anyone who wants to use their TV as a display. JROK's units are very good for this conversion.
Hope that helps

I wired my Jrok + my jamma harness to a PCB connected to TV
I hooked the AC plug to AC on the Psu + the middle pin to FG (FRAME GROUND)
+ the jamma wires to +5 +12 & ground
i wired one speaker
just to Test run...
but im scared to plug it haha
Still shaky from a exepirement that went wrong last year
& got buzzed off a good Zap of AC direct voltage
ahhh i got to do this ;)

Thanks BobA, glad to hear any info from someone that has built one. :wink:
