Arcade1Up SPINNER and TRACKBALL MOD Upgrade for Centipede, Tempest or the 12-in-1 Deluxe
UPDATE: As it turns out, you don't need the interface board for this unit. Just for PC.
See how easy it is to upgrade and replace the Arcade1Up 12-in1 Deluxe spinner and trackball for MUCH improved gameplay. Seriously, SUPER easy. These products also work with the Arcade1Up Centipede and Astroids unit. I tried the cheap or free ways to improve the spinner but they don't help much.
I got a demo model and the deck decal was very worn, so I also replaced the decal and added a deck protector:
