I currently have one vertical cab (Galaga/Ms Pac reunion) that is dedicated to 4-way one fire button games. I recently purchased another vertical cabinet on Craigslist (file attached) to for a restoration/build based on dual 8-way Wico leafs(SHMUPS) and one 2.25" trackball for Centipede/Millipede. The current control panel atrocity on the cabinet will be dumpstered, with a custom panel to replace it.
I would like to stay with 2 buttons unless there is a must have 8-way vertical game that uses 3 buttons that eludes me off the top of my head. Are there any killer games that require 3 buttons?
The control panel has a lot of real estate, but I am not a fan of overwrought control panels. However, I would like to add a spinner, but I am unsure of placement. I really like Arknoid, Tempest, and Breakout but not on a trackball.
Where do people normally place their spinners? I want the layout to be joystick, button 1, button 2, trackball, joystick, button 1 and button 2 with the trackball being centered. I thought that the spinner could go above the trackball. Since there won't be any bowling or Golden Tee games, I don't think a spinner above would interfere. Maybe off center to one side might be better just in case. Thoughts/opinions?
And no, that's not my garage sell garage

That was from the CL post.
