Replacement Encoder Wheel
(1/2) > >>
campbelldave:
Hello,

I recently rebuilt 2 Atari trackballs that looked to have once been part of a Marble Madness control panel.  They work fine now, except 1 trackball had a damaged encoder wheel (it was slightly bent and I cannot straighten it out).

Does anyone know where I could buy a replacement encoder wheel or does anyone have any extras for sale?

Thanks!

Bob Roberts has a set of 2 for $6.00.

I'm sure divemaster carries them as well but I was unable to find a part number on happ's site.

The bending hardly ever effects the proper function of the wheel. Mine aren't entirly straight either, doesn't matter at all. The opto-electronics will still "see" the holes and notches pass through.

Very true.  It would need to be bent pretty badly to no longer work well.  A hair dryer, carefully applied, will likely also warm it up enough to allow you conform it to a flat surface.

But if not, I have a plenty in stock.  Don't mind the shipping price if that's all you need.  It would be adjusted down and sent in an envelope.
