Alright so I am waiting on getting my T-Molding before I begin wiring the control panel up to a Hagstrom trackball controller and a Hagstrom keyboard controller. This is going to be my MAME cabinet from running trackball games.

The question I have is in regard to the Atari cone buttons. There are four wires: two white, one black and one red. So I get that black is ground and the red is daisy chained to the trackball which I will wire up to the trackball encoder's 5v pin. But, what are the other two white wires for? I'm making the assumption that one will be wired up to the keyboard encoder to send a keystroke for player 1 or 2 start. If that is correct, then there is one white wire whose function is not accounted for.

And just so I understand why there is a 5v wire to these buttons, is its purpose to light up the cone buttons?

On the Benson trackball, I have documented that the wiring should be oriented bottom right towards you with yellow being X1, green X2, brown Y1 and blue Y2. I got that info from Googling another forum post so if someone could confirm that's correct...

Lastly, if anyone has worked with the Hagstrom trackball encoder, I noticed they labeled their pins A1, A2, B1, B2. Does A1 map to X1 and B1 to Y1? I can always call Hagstrom if noone knows...

thx in advance,

Rob
 
Two wires are for the light and two wires are for the switch

Two ground wires... one positive lead for the light and one lead goes to your encoder (for example P1 START)...

BTW - I use Volcano's in my Multipede which is an arcadeshop multigame board based cab... not MAME. You're only going to get a solid light BTW... I don't think MAME is equipped to handle the flashing, etc... but I could be wrong... that said, if it is, SOME sort of hardware would be required... something like what they use for lit buttons, joysticks, etc...
 
Thx for the info

The most important thing is the input for 1 and 2 player start so if I am not able to get the lights to work then no big deal...I believe someone else mentioned that I could wire it up to the PC power supply but I would have to put a resistor inline. I have wired up the coin door lights to my PC power supply so that's pretty easy.
