JAMMA female-female adapter?

[s34n]

Hi

I hope this is the correct forum!

I just bought a JPAC for an arcade cabinet, however, my cabinet's jamma connector has a male end, and so does the JPAC. Is there a simple female-female jamma adapter on the market? I checked around but I couldn't find anything! I really don't wanna to re-wire it

I've NEVER seen a JAMMA connector with a male end. Can you snap a pic?

See attached!

I think it may be a little more complicated in retrospect.

I am trying to replace this IO with a JPAC, I believe those white plugs accept joypad input and the male jamma end doesnt have evrything i need. I dont really want to cut all the plugs up because I would like to but the old system back in now and again.

That is not jamma.

[yotsuya]

That is not jamma.

Yep. Someone made that for ease of plug and play.

[s34n]

In your experience, what would you recommend to get this working with a JPAC? I would like to be able to still use the original parts in the future without much effort in re-wiring again

[Nephasth]

Cut the wires. Roll your own.

Wire in a real JAMMA connector.

Just go to a parts supplier like Jammaboards.com and get a jamma harness.
They're cheap and already have all the quick connects crimped on.

I've never seen a male connector on a cab before. But yeah, it ain't JAMMA. God knows what was plugged into this?!

It's in the link in the OPs second post. What the hell is that? I see three micro button, one labeled test. There's what looks like a spot for a hard drive power supply plug, are those spaces for PATA connectors? I can't even identify what the clusters of three solder points are for. And that looks like a huge array of... capacitors?

I wanna see more photos of that thing and the cab it came in. It's like some weird mix of old and new tech.

It plugs into a Pump It Up Jamma PCB Assembly. (but its not Jamma right?)

Mine from an early Pump It Up machine, basically a Pump machine that uses an MK3 main board. Later, they produced MK5, MK6, and MK9 in later machines.
The TX machine in the post above uses an MK9 main board I believe. The Pump It Up Jamma PCB Assembly on the MK3 (Which I have), is incompatible with MK5/6/9, but it kinda looks the same.

Even though this isn't a real Jamma connector(?), it plugs into a Pump It Up Jamma PCB Assembly (So this really confuses me???)
http://www.arcadespareparts.com/arcade_parts/machine_parts/pump_jamma_pcb/12489.html

The Pump It UP Jamma PCB connects to a Pump It Up IO Assembly via two mini 'floppy drive' cables. This, in turn, connects to the main board (MK3/5/6/9)
http://www.arcadespareparts.com/arcade_parts/machine_parts/pump_it_up_i_o_pcb_assembly/12486.html

The reason I bought a JPAC, was because the Pump It Up IO Assembly is out of stock and really hard to obtain. Not to mention, I need to order it from Asia as I cannot find a US supplier. The IO and Jamma PCB are around $100 each plus taxes and shipping.

Granted that you cannot play official Pump It Up games using a JPAC as the Boot Loader checks for official hardware, this is a personal machine uses at home which I plan on running Open Source software instead, like StepMania.

Sorry if it's too much info!

I don't use this forums much, but it doesn't take a genius to figure out why your post count is high. I think you should focus on adding some substance to your posts, they offer little to no value at all (My opinion is based on this thread and a couple of others where I have looked up your name). Just a tip for you, don't take it the wrong way... I am here to help you if you need any assistance, send me a message and I can guide you a little better.

If we could get back to the topic now if more can be added, otherwise, the thread can be closed. Thanks

Neph has added a lot of value to this board in regards to wiring, crimping, and LEDs. He is a straight shooter and tells it like it is. I suggest you read more of his posts before you pipe up.

[Nephasth]

I'm no genius, but at least I know how to use a search function. Google JAMMA sometime brainiac. Have fun with your dance offs.

Now here, have a granola bar to help settle yourself down before nap time.

If one were to assume that that really is a Jamma board, I'm not going to sit here and count pins or read a manual for a game that... well... looks like it involves a lot of excercise.

So if we assume a JAMMA connector, it's obvious what the fingerboard is for. It's a simple gender bender.

Not saying it's JAMMA though.

When I first saw this topic, I laughed and thought about what my friend and I have come to call the "jacked-up harness" (as a vauge reference to "JAMMA harness") that Pump It Up uses.  I figured that was too crazy specific to be what you have, but indeed you do.

It is not fully JAMMA, but it's pretty close.  I'd have to grab my wiring diagram to confirm if it would at least not break things, but you could potentially just get a fingerboard and solder a couple eyelet connectors to both ends to make a "JAMMA gender changer".

Lights are on 3 separate connectors.  I don't remember if you have to do anything with them to make the stage IO usable.  DDR (which, for hysterical reasons, is almost identical) requires connecting a couple pins together, at minimum.

It is, however, compatible with the newer Mk5/Mk6/Mk9 system units.  They didn't change anything but the audio and power wiring between them.  Mk3 uses a couple of 0.084" (HDD drive style) connectors from power supplies mounted down in the cabinet.  These are found only on the SD, DX, original SX (not the neo-SX) and early GX cabinets.  Audio was from a proprietary header on the interposer/EMI filter board into which the jacked-up harness connetors (but a separate connector).  I don't remember what Mk5 did, but I think it had an internal power supply being fed 220V (yes, 220V, NOT 120V - make sure you've got the power supply set right if you swap it).  Mk6 and newer are basically just small form factor PCs.  You feed 220VAC to a TFX formfactor power supply and pull audio off a standard 1/8" stereo plug.  If you've got the appropriate audio breakout cables and power supply in the cabinet (you can just use an old PC supply, if you don't), you can freely run Mk3/Mk5/Mk6/Mk9 in the same cabinet.

FWIW, if you need more info, I know basically everything there is to know about the GX and neo-SX.  I've also poked around quite a bit in an old SX and some in a DX.
