Just create combinations you know you will never do by accident during the actual game. It can't hurt to put the games on free play and eliminate coin altogether. --- End quote --- Ahh, the ol' free play. I hadn't even thought of that, thanks! |

It comes with wiring for 3 buttons and spade connectors are included. They work well IMO and are good value at $15. https://www.sparkfun.com/products/10758 --- End quote --- --- Quote from: Bambam1963 on October 26, 2013, 03:14:05 pm ---You could hack a keyboard, but it really is not worth the effort. You will need one eventually if you want to try other games. An i-Pac 2 is pretty cheap and easy to set up. --- End quote --- Yea, I didn't want to hack up a keyboard if I could help it. I do have other cabinets with ipacs/keywiz, so I know exactly what I'm missing by not having a joystick and lots of buttons. This is to be a dedicated trackball cab, and the pc I have to use does not have ps/2 port, so I'm trying to find ways for a usb trackball w/3 button support to work out for both game play and simple admin needs. |

Several of the KADE firmwares support PS/2 trackballs like the Sparkfun trackball -- see this thread for details. That leaves you lots of AVR inputs for whatever you want. If you're handy with a soldering iron, you can also buy an AVR from another vendor and use KADE Loader program and firmwares. Scott |

If you are doing a whole cabinet then I wouldn't hobble the project down to 3 inputs just to save $25 on an encoder. |

This is to be the next project for the 'Arcade Fired-Up' course I'm teaching, and we are on a fixed $300 budget. The pc and monitor are already secured, and I have a bit of scrap wood (not enough for full sides of even a lowboy/cabaret), but trackball setups (esp. the usb ones that don't need mounting plates) are not cheap and when you throw in buttons, switches, wiring, t-molding, paint/stain, screws, marquee retainers, and especially plexi, glass, and printed artwork that $300 goes fast. Can anyone else comment on PL1's post? I need to do some research there. |
