Title: Help with Betson trackball to Opti-Wiz (solved)
Post by: spystyle on February 13, 2010, 08:13:44 pm

Hello from Maine,

Gosh this is my first trackball :)

So I am reading the sheet of paper that came with my Opti-Wiz and looking at this Betson trackball and I could use a clue...
 
Here is what I'm looking at :

The top and bottom are shown just for fun, it's a Gauntlet Neo Geo Centipede reunion panel :)

Here is the Betson plug and the Opti-Wiz board, I have to get these two together

I need a clue about these wires, the top are green, blue, and brown

Aha! I found the answer :)

X-axis makes your mouse move horizontally
Y-axis makes your mouse move vertically
Z-axis is like the scroll wheel on your mouse

I want just X and Y for this trackball

Yellow = X1 = A on Opti-Wiz
Green = X2 = B on Opti-Wiz
Brown = Y1 = C on Opti-Wiz
Blue = Y2 = D on Opti-Wiz
Red = +5v = 5v on Opti-Wiz
Black= ground = symbol above 5v that looks like this :

And that looks like this :

When I tried the trackball out in Windows XP the mouse cursor was inverted, the cursor would go left as I was spinning the ball right - so I flipped the trackball in it's plate and tested again, it worked fine.

I know MAME is super configurable so I will make player three's buttons as mouse buttons that can work within Windows and also be set to work within MAME - this acts as a mouse built into the control panel for using in Windows.

On the button's microswitches "NO" lugs connects to "L" and "R" on the Opti-Wiz, and "COM" lugs connect to the nearby ground symbol.

Hot glue is nice for holding wires down, and removable in the future if necessary.

And that's a wrap :)
