[comp.sys.atari.st] Trek Ball

dm@pnet01.CTS.COM (Dan Melson) (07/14/87)

I have a slight problem.

The wilderness of my desk is no place for a tame, god-fearing mouse.

I would like to know if there are any commercially available trek balls
available which will function as the mouse (two discrete buttons, etcetera).

Does Atari make such a beast? (If not, they should!)  If not, are there any
third party products in this line?  I already know the trek ball that works
with the 800 is entirely unsatisfactory (loose controls, among other things).

If there are none made, does anyone have any experience with wiring up one? 
I'm thinking of asking my employer (the FAA) where they get the Trek balls
that go with the radar scopes if nothing else works out.  Nice tight  action
and two discrete buttons, so I know they're made somewhere.

After converting one of the Atari trak balls to work with the ST (and
replacing the cord so I got both buttons :-)  I found that the trak ball
takes as much, if not more, desk space than the mouse would.  Of course,
one could use the trak ball in his/her lap, but then I an using a rigid
mouse pad that the same could be done.

The Wico trak ball is smaller, but almost impossible to find.

I've also picked up a couple of different brand mice, and hooking them up,
the 200dpi take about  1/4 less room to move full screen, and the 400dpi
take 1/2 of that.  The 400dpi mouse could use an SF354 as a mouse pad with
lots of room left.
