Ultimarc trackball and mousehack?

Pages: << < (2/2)

Popcorrin:

I actually ordered the non-minipac trackball.  I have used a mouse hack with a happs trackball before and it worked fine.  I assumed the ultimarc ball would hook up the same but so far I haven't had any luck.  
Crashball, I grounded everything to the ground pin on one of the button switches.


lcddream:

when i did mine i followed minwah's tutorial on mamewah.mameworld.net...got it working on the first try no prob. If you havent already try grabbing power from the pc power supply.

Mickey Juice:

I had trouble doing this, but (the problem was) I wasn't using pull up resistors.

This might help:
