Great deal here! I just paid $40 for 2 new optic boards, not including shipping. But if they are green optic boards, they won't work with the trackball header on the 60 in 1. Go with the newer red optic boards.
Yep, they are green Atari opto boards.. Bought a box of them from an op a while back.. He had tons of trackball nos parts.. Have 25 sets of rollers for 2.25, 2.75, 3" and more..
