: THIS MESSAGE HAS BEEN POSTED AGAIN TO GET AS MUCH FEEDBACK AS POSSIBLE. : Sorry guy’s who have responded to this message in the past. I just would like as much feedback as possible on people’s opinion on their Track ball or people that have built cabinets. : These questions below arise from the fact that I would like to integrate a Trackball into my control panel that acts / looks / fees like the original arcade cabinet trackball like Marble Madness. : My questions are: : 1. What HAPP Trackball size (2-1/4, 3” or 4-1/2) do you use in you cabinet? : 2. If you had a second change to change the trackball in your cabinet, what size would you install (2-1/4, 3” or 4-1/2)? If not why not? If so why so? : 3. The HAPP 4-1/2” Trackball, is the ball able to be pulled in and out freely once the Track ball is installed into the control panel? Looking at the HAPP 4-1/2” catalogue picture it looks like it can. Can any who has a 4-1/2” version confirm this. : 4. How heavy is the ball in the 4-1/2” trackball? Is it heavier then the 2-1/4” and the 3” balls? It got mentioned that the 2-1/4” ball is heavier then the 3”, first allowing it to free-spin longer. : 5. The two HAPP trackball (3” and 4-1/2”) are constructed and operate differently. Which is the most durable/strongest version? : I’ve asked the following question before, but I was away and cannot fine it on the message board: : 6. What is the Trackball size in the original Marble Madness cabinet? : 7. Any other feedback on Track ball would be kindly appreciated. : Kind Regards : Dariusz
