Ultimarc trackball review?
(1/6) > >>
jcoleman:
Has anyone had luck, good or bad, with the Ultimarc trackballs?  They're significantly cheaper than Happ's units, even with shipping.

Thanks,

John
SeanCyrusTowel:
just for a note, they are not 3" they are 2 1/4" which is the standard pool ball size :)
GGKoul:
Yep.  If you order a ball from Ultimarc order the plate as well.  As 2 1/4 plate can be hard to find.
gmorse:
I'm very happy with mine.  Only thing to keep in mind is if you hook it up to a mouse hack, you'll need to use a 2.2k pull up resistor on each x and y line.  Took me a while to get the thing to work because of that, but it's well worth the money.

Definitely order the mounting plate as well.  I didn't and it took me quite a while to jury rig a solution.  Would have saved a lot of grief.
jcoleman:
I'm actually planning to mount it in one of the Multicade trackball panels over at www.arcadeshop.com (which require a 2.25" trackball), so I won't need the mounting plate.  I'm also hooking it up to a MiniPAC, so the resistor shouldn't be an issue.  Thanks for the responses!
