This is the first arcade cabinet in a while that I cant recall ever seeing in a arcade.Kinda of odd control panel, was this game any good and whats with that roller thing?

It's basically a 2-way trackball, which is why the Tempest spinner replaced it so easily on the conversions.

I recently won an auction for a roller controller from a Stern Moonbase. I'm thinking about installing it on one of my cabs but its so much bigger then the Major Havoc one that I don't know how accurate it would feel. The roller for Moonbase is bigger then a hockey puck and is seriously weighted. Also there actually is a 2-way trackball which can be found on Midway's "Kickman/Kick"

Isn't a roller more like a spinner on it's side rather than a 2-way trackball? That's at least how I would do it since a spinner has a codewheel connected to shaft and 2-way trackball would need a pickup wheel to read the ball motion (which makes the spinner much less prone to problems)

No.

The MH roller is basically a really big skateboard wheel, and sits cradled on two idler rollers, while driving a third roller that has an encoder wheel on it.
That is closer to the function of a trackball (input device sits on top of rollers, and turns them) than a spinner (input device is on the same shaft as the encoder wheel).

I did do a B.Y.O. proto of a MH controller awhile back, using a 3" caster for the wheel.
I ran a single shaft through it, with an encoder wheel on the end of it.
I wanted to see if you HAD to have 3 rollers to make this work, and proved that you don't.
The one I built was very similar to a spinner, turned on its side, as you described above.
