The old Trackmans have very limited inputs relative to modern gaming mice. There are some trackballs with scroll wheels, but they have different ergonomics (you rotate the ball with your thumb rather than your index, middle, and ring fingers) that my buddies aren’t fond of.
Given that theirs is a very niche use case, I don’t think anybody’s gonna make a trackball to suit them that also has a scroll wheel, but I guess if somebody was motivated enough, there’s an opportunity for some sort of ESP-based open source hardware.
