[comp.sys.atari.st.tech] Microsoft mouse and the ST

tech002@.ucsc.edu (10020002) (01/25/91)

I have a slight problem here.  Just recently, my mouse went the way of the
dinosaurs and I don't really have the money to buy a new one right now.
(It sucks being a starving student.)  I remembered that someone had said
that the old Microsoft mouses were compatible with the ST's mouse so I 
chopped off the female end of my mouse and put it on the Microsoft one, since
it originally had a male end.  I hooked all of the wires up (except the red
one, I believe it is a 5V supply for the Atari mouse but the Microsoft one
is a purley mechanical mouse, not opti-mechanical) and it works almost
perfectly, except that occasionally it makes jumps on the screen when I
use it.  It is like there is some voltage or current jump or something 
going on (I don't really know how they work.)  Anyway, I was wondering if
anyone else had ever had any problems like this or had any reccomendations
for a solution because I would really like to have a steady mouse to use.
I thought of putting some capacitors accross the UP/DOWN and the ground.
Does anyone know if this would eliminate spikes, given the correct farad
capacitor, like is used for decoupling capcitors in circuits?  Any
help would be greatly appreciated.  Thank you.
