Need Help to Hook up Trackball

[Vicious Burger]

Hi all,first post here. I'm renovating a Taito Pacman (converted to Big Event Golf) cabinet (will be posting pics soon) and I am making a custom control panel with a PC inside the cab to run MAME. I have most of the parts for the CP, joysticks, USB spinner,buttons etc,and I have a USB trackball but it means using the one from my X-Arcade console,which would basically render that useless.
Can't afford to shell out $100 right now for a Happ 3"USB,but I can get a decent used non-USB one cheap,but not sure how to hook it up.
There is a trackball in the CP from the Big Event Golf game,but its only a small one and i want to put a 3" in there.
I have an IPAC4 to connect the joysticks and buttons,but if i get a trackball from another arcade machine,how can I connect it up to work with the system along with the IPAC if its not USB connectable?.  If its a pain in the you-know-what I'll just use the one from my X-Arcade and go via USB

thanks

there are PC interfaces that are designed to work with most arcade trackballs...

mainly the OptiWiz from groovygamegear.com, and the opti-pac from ultimarc.com

I own and love several ultimarc products, but i have not personally used their trackball interface.  i do have an optiwiz in my cabinet and it works great...plus it is only like $15

The minipac from ultimarc has a trackball/spinner interface built in along with the button and joystick interface.

Thanks guys,the OptiWiz sounds like the one I need,since most of my other connections will be going through the IPAC,I won't need anything too fancy for the trackball connection.

Found a used Happ 3" trackball,but it has an AMOA connection on it. I saw a USB interface adapter at arcadeemulator.net but its like $43 for what amounts to a bit of wire with a plug on it.

Is there anywhere else that sells the AMOA to USB/PS2 adapter cheaper? I couldnt find one. If anyone has a spare one for sale maybe?

I was thinking of getting the Optiwiz,($15 woohoo!)does anyone have a diagram of how to connect a Happ trackball to the Optiwiz if i cut off the AMOA plug(s) and go that way ?

I am not familiar with the opti-wiz, but found this on GGG website that might work (I think) somebody correct me if I am wrong.

Hope this helps.

I use the ultimarc opti pac, for both my spinner and trackball.  Easy install, great product.
