Got it used from SWFA and no documentation [img]/ubbthreads/images/graemlins/crazy.gif[/img]
Kirby has maybe one at least if I remember correctly.
Just put the big end in the front and it'll do fine [img]/ubbthreads/images/graemlins/smirk.gif[/img] [img]/ubbthreads/images/graemlins/smirk.gif[/img]
The dots are 0.2 mil diameter and 10 mils from post to post.
Clicks trak well an are 1/8", I think. Or maybe its 8 clicks per mil. Like I said I have no documents either.
Much more than that confuses my little mind.
Go here for an eye opener. They are still around but even amazon is looking for manuals. Check out that price!!!Link
