4.50" Trackball Assembly
« on: December 22, 2020, 04:53:59 pm »
Hi there. I'm wanting to find how I either make a 4.50" atari trackball assembly or BETTER YET purchase it from someone/somewhere. I'm wanting to use it for my retro-pi missile command. The 4.50" ball felt so right when I was playing this game. anything else is just gonna detract from that feeling I had. I can get the ball and shafts but literally I cannot find anyone out there that will sell one to me.  The optocouplers and boards  and encoder wheels have been made of unobtainium.

I'd rather not use the 3" if I could somehow get the 4.50"
does anyone have a idea?

I saw one online with a control panel for about $500.
Formerly known for the (apparently now defunct) arcadeartlibrary

There must be a few Missile Command fans among the Mame dev crew apparently because there is a game specific setting for the ball size you are using.

Between that and the other sensitivity settings you can get a good 3" ball to feel just right.

Unless you are a die hard purist for that 4" ball then you can actually save yourself some expense and drama that way and not be disappointed in terms of playability.
Why'd you kick me?
Where's your brain?
