Atari Optic PCBs
D_Harris:
I have a lot of "junk" Atari trackballs from games like Millipede and Centipede, and I plan to use some of the optics for s couple of spinner control panels for MAME.
I haven't tested the optics yet but is it common to use them for MAME CP spinners?
And are these optics easy to repair. (They seem simple enough).
Thanks.

Nephasth:
If you've got "junk" mice laying around, you can do this. No optical interface required.
Vigo:
Converting a trackball to a spinner does not sound like the best route. I would say sell the trackballs as spare parts and put the money towards buying a real spinner. Or build your own as Nephasth points out.
D_Harris:
If anyone has ever used the Atari optics from a trackball for a spinner I'd appreciate your experiences.
Thanks.

I tried to, but the board I had (from a Centipede) was incompatible with my minipac encoder. I spoke with Andy and he informed me that among optic boards there are those that pull high and those that pull low. The minipac only did one, I can't recall which, but the optipac did both.
I ended up using a board out of an Imperial trackball and using a bit of metal to hack up a little offset arm to make the different sensor line up:
What encoder are you using?
