I have a problem. You see i have a lot of disk's and diskboxes and diskdrives
and all kind of things on my writingdesk beside my Amiga.
This decreases the moveability (is it spelled that way) of the mouse.
So i wonder if it shouldn't be more comfortable with a trackball.
The trackball is a device similar to a mouse that is upside down,
where you instead of moving the mouse, spin a ball very like a billiardball,
that is placed on top of the device (The device itselfs is stationary and
doesn't move).
  I know that the trackball exists to a lot of other computers such as the
Macintosh and pc, but so far i haven't seen it available to the Amiga.
I've found an old 'Wico trackball' (joystick compatible) and i am thinking
of rebuilding it to be compatible with the amiga-mouse.
The Wico have those wheels with infra-red??? sensors similar to the
mouse, but instead of giving the correct mouse vertical and mouse horisontal
signals required, it gives out pulses to the joystick up-down resp.
joystick left-right pins in the joystickport.
If anyone knows exactly how the amiga-mouse works, which signals it gives
out and on which pin's, then i would like to share your knowledge.
  I also wonder if there exist any trackballs that are ready to buy and
compatible with the amiga-mouse already, and in that case where to get one.
If it do exists then please let me know the price of it,
and where to get it from.

Thanks in advance.
