2.25 Inch White Ball Arcade Game Trackball Compatible with Jamma 60 in 1 Jamma

Great addition to 60-in-1 Vertical! Get this with a custom control deck and 60-in-1 vertical jamma kit. Works great for centipede, arkanoid, 1943 and more. Following other suggestions I mounted the wording upside down and then plug-n-play I didn't have to change a thing in settings. secure with with screws provided, but u might need washers - https://www.amazon.com/gp/product/B07HVRJW5J/ - I used this kit for the speakers and the M3 or M4 washers for this - (black finish) look great.

Works great with arcade1up jamma kit, i did install backwards first, the writing on top of unit should be upside down when you looking at it from top facing screen.

This is a easy to install, easy to use trackball, functions great and rolls smooth. I did install upside down at first and the screws were a bit of a problem. I couldn’t ask for more! Great product!!
