Not all of the buttons are wired up in the 6in1. I think the test/service buttons are missing/won't work (among others?)
Can anyone provide a list of pins/buttons not supported/missing by the switcher board? I thought it was just a straight 56pin to 56pin (with the exception of the -5v)
If the switcher does not support these pins, can anyone provide a list of pins supported by the switch?
Can i just 'jump' the pins on the underside of the switcher board as a worst case scenario? What are potential problems?
I got a reply from Tim Hensel regarding this:
The 6-in-1 MultiJAMMA Switcher PCB basically uses a standard JAMMA Pinout with some extra pins: http://www.jammaboards.com/jcenter_jamma_pinout.html
It does not use these sometimes used JAMMA pins: E -5VDC 5 -5VDC J COIN COUNTER #2 (Rarely used anymore) 8 COIN COUNTER #1 (Rarely used anymore) K LOCK OUT COIL #2 (Rarely used anymore) 9 LOCK OUT COIL #1 (Rarely used anymore) 15 TEST SWITCH
It does not use these pins which standard JAMMA does not use either: M N/C (Not Connected) 11 N/C (Not Connected) S TILT (SLAM) SWITCH
Extra pins it does use that are not standard JAMMA are: c Player 2 Button 4 25 Player 1 Button 4 d Player 2 Button 5 26 Player 2 Button 5
All other pins are normal used and follow the correct JAMMA pinout functions.
You can wire in extra wires for other microswitches/functions similar to how the -5VDC is wired except if wiring to more than 1 slot then you would need to put a diode (such as a 1n4007) between each slot JAMMA pin and the main edge connector of the 6-in-1.
Example If you wanted to connect extra buttons to PINS 11 and M for two slots:
SLOT 1 PIN 11 *------|-------* (Pin 11 of main edge connector)
SLOT 1 PIN M *------|-------* (Pin M of main edge connector)
SLOT 2 PIN 11 *------|-------* (Pin 11 of main edge connector)
SLOT 2 PIN M *------|-------* (Pin M of main edge connector)
***The diode is needed to prevent the other installed PCBs to interfere with the selected board.
I hope this information helps!
