Here is the pinout for Ikari Warriors (44-pin SNK):
Here is the pinout for TNK III (also 44-pin SNK):
So the TNK III board works fine in the Ikari Warriors cabinet, i.e., the joystick controls the tank movement correctly, and the rotary handle controls the aiming of the turret correctly. +5V, ground, RGBS, P1 & P2 start, coin, and speakers are all in the right place as well. However, the two fire buttons don't work for obvious reasons. I have a few questions:
1. If I wire up the Ikari Warrior's card edge connector pins 25 & 26 to the fire buttons (in parallel with their normal wiring to pins 13 & 14) for use with the TNK III boardset, will that cause any problems when the Ikari Warriors boardset is installed? In other words, pins 25 & 26 aren't used on the Ikari Warriors boardset, but with this proposed setup, pressing e.g., the machine gun button when playing Ikari Warriors would close a switch on not only pin 13, but on pin 26 as well. Is this a problem? If it is, I could put a Molex connector in there to easily disconnect the TNK III fire buttons wires when using Ikari Warriors.
2. There is currently +12V on pins 39 & 40. TNK III only calls for +12V on pin 40. Is that a problem?
3. There is currently -5V on pins 29 & 30. TNK III only calls for -5V on pin 30. Is that a problem?
