WTB: Jamma Switch Board for at least 2 boards

[Tyrem]

Heyho from Trier again!

I am working on my Jamma Hellomat Track & Field cab at the moment. Since I have Hyper Sports, too and since the pinout is the same it would be great to run both boards at the same time in this cab.

Can anybody of you guys out ther recommend a board for me capable of running the two pcbs at the same time?

Thank you in advance!
Stefan

I have to check, maybe I have one, get back soon.

cheers mate!

I think both games have the konami pinout, so a Jamma switcher will not work with those

or maybe if you make/buy two Konami-Jamma adapters ?

Dont know if that works

sure, i have the konami adapters and as far as i know they work fine together with aswitch-board. several people ars using this combination.

I have these, you just have to solder a switch somewhere (forgot where ), maybe it is that yellow stripped loose wire on the left.

cool! if it is still working.. I would love to take it. how much do you want for it?

[Etienne MacGyver]

Does someone has a schematic of this ?  i mean it looks easy enough to build with some parts

i see a chip, 4 relays i think, 3 resistors, a capacitor and a voltage regulator or maybe its a transistor or a triac.

or bela, draw the schematic for us

There are versions of the Hellomat with the possibility of playing two PCBs in one cab, I guess you could upgrade your Hellomat, provided you can find the needed parts.

Yes, the schematic should be quite easy. Is that chip a 4066 or sort of analogue switch? Then the yellow wire should be connected to the resistors. I guess the resistors are 10k pulldown to GND or pullup to 5V , depends how the data select line of the chip is specified.

What are the transistors for?

hmmm, do you happen to have some pics?

[Belike]

You can have it for the shipping price.
I made some more pics and I realized, that it is a hungarian product, lol.







I also checked the control panel of the parted out machine where it came from, it has a button with 2 wires, one goes to the ground circle of the joystick microswitches and one is loose, I guess it goes to this adapter somewhere.

Do note that this board powers BOTH boards at the same time. Your power supply will need to be able to feed both PCBs without problems.

It was connected to a Hantarex MTC 9300 psu and chassis 2 in 1.

woha.. thanks mate!

pm for the rest?
