Due to many requests, I have dragged this out and reposted it.  I was not
the original poster.  Please send me some mail if you successfully make 
one of these adaptors, I intend to give it a try in the future.

Subject: Here's how to hook a MicroSoft Mouse to a ST
To: info-atari16@score.stanford.edu 


Well, here is how to connect a Microsoft Mouse to an Atari ST.  (520/1040)
The Atari has a 9-pin D-type connector.  The Microsoft Mouse has a rather 
strange connector on the end.  To prevent having to cut the mouse cable up, 
I made this adaptor.  If you still can't follow it, please let me know and
I'll try to redescribe it.  This does work for me.  I've been using it for 
6 or so months now with no problems at all.  It does take some soldering
skills, so if you're not so hot at soldering, find a friend to help. 

As far as I know, this does not effect your Atari's warranty.  However, I 
have not asked Atari. :-)

* = I am not sure why I have pins 6 & 1 tied together, but it does work. 

The Microsoft mouse connector looks like this.  This is the solder side, 
with the leads pointing up.

  If you can not use the connector, the pins are numbered as follows.  This
  is the connector side from the Microsoft Mouse plug:


      /------------\    This is a view at the front of the connector. 
     / Blank "KEY"  \    It is where the plug from the mouse would be.
    /----------------\    The pin labeled 'n' is not connected.
    | n   4   X   8  |    The place labeled 'X' is filled, and does not

Have fun!
