4 Player IGS PGM adapter (cable replacement)

[Barth0lin0]

Hi guy.

I'm a proud new owner of a V14 IGS PGM board.

Looking for an easy way to plug a 3rd and 4th player for all the beat em up greatness!

I find the OEM cable unpractical to play with a supergun so i dont want to spend on it ( I use V1.7 minugun supergun)

Ordered a bunch of 34 pins connector and DB15 neogeo connectors to make a custom cable.

Also found that RGB is selling his adaptor for the HAS and this http://projects.trurip.org/?page_id=37 with a custom pcb .

Is there any open source PCB project in the universe? If not maybe someday I could try to design one...i'm no expert....but this looks like basic routing!

gimme your input!

thx

Simon

I'm in the process of designing a 4 player adapter for the Minigun...

yes man!!! Super news ! I'll let the real professionals do the job! Will buy one from you day 1!

thx!

I'll be posting some details soon, probably within the week. Should be ready for production and testing soon.

Here's what my 4-player cable looks like. You just need a spare jamma harness and some DB15 connectors. It's really nbd.

I bought a pcb someone made just for this about 3 years ago... and sold it a year ago. I would’ve thought it’d be more massed produced after RGB came out with his.

 

[Barth0lin0]

Decided to make a custom one with a IDE 34 pin connector and 2 DB-15 connector. A lot of small soldering but easy project!

Is there a pinout available for this connector? I want to build a 3p and 4p DB15 plug, similar to what @Barth0lin0 made.

Also looks like someone else did this here:

mine looks similar to the one in this ebay listing. Followed the same source that @djsheep just posted

Don't follow that pinout, it's backwards re pin numbering.

Not sure I understand. Are you saying pin 1 starts on the right side of the connector vs the left or something else?

 

[Frank_fjs]

I'll have to dig through my notes but it was something along the lines of pin 1 is labelled as pin 34 and vice versa.

I've been looking to make up a cable to link 2x cabs up for some 4 player fun also.
The official cable seems crazy expensive, I'm sure I found the pinout online for it. The only question mark is the white component on the player 3/4 machine's fingerboard. A voltage regulator perhaps?

it’s a big resistor to put some load on player 2 cab.

Does anyone know if this was fixed since that post?

Does anyone have the _definite_ pinout? All Google searches end up either at junkerhq or arcadeotaku:

and
https://wiki.arcadeotaku.com/w/IGS_PolyGame_Master

Edit:
Based on the drawing pin 1 should be top right if the notch is at the top:
https://multimedia.3m.com/mws/media/22448O/3m-four-wall-header-3000-series-100-x-100-ts-0772.pdf

So the junkerhq pinout should be mirrored horizontally:

Top row	Pin	Pin	Bottom row
GND	33	34	Speaker +
GND	31	32	Speaker +
Blue	29	30	Green
Red	27	28	GND
GND	25	26	Sync
Coin counter 1	23	24	Coin counter 2
Test	21	22	Service
Player 3 Button D	19	20	Player 4 Button D
Player 3 Button C	17	18	Player 4 Button C
Player 3 Button B	15	16	Player 4 Button B
Player 3 Button A	13	14	Player 4 Button A
Player 3 Right	11	12	Player 4 Right
Player 3 Left	9	10	Player 4 Left
Player 3 Down	7	8	Player 4 Down
Player 3 Up	5	6	Player 4 Up
Player 3 Start	3	4	Player 4 Start
Player 3 Coin	1	2	Player 4 Coin

The part used on the motherboard seems to be this:

(Edit: This pinout seems to work.)

Can you do me a favour and check which pins Speaker- from the Jamma edge is connected to?

Speaker - on the jamma side is connected to all of the ground pins on the system side of the cable.

Just wondering if you ever made a adapter for P3&P4?
If so I would love to purchase one!
I tried to make one with a old floppy drive cable which sort of works but the wires break far to easily!

 

[Flinnster]

I used 3D printing ribbon cable for my link loom, it's pretty robust. My link loom was just standard jamma for players 1 & 2 across two cabs mind, I've not attempted to make a PGM 3 & 4 player one just as yet.
