Subject: How to hook-up a MicroSoft mouse to an Atari ST

Here's a repost of my article of wayyyy back (Feb 1989) on how to hook
an Microsoft mouse to an Atari ST. No software changes are required.
All it takes is creating a special cable between the mouse and the
Atari.
I've been using a Microsoft mouse now for around 2 years on my 1040,
with nary a glitch. It's so much better than the Atari mouse, I'd never
go back. (IMHO)
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 [Note, it's been 2 years
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.
Atari ST Microsoft Mouse ST expected signal
1 5 XB
2 3 XA
3 8 YA
4 9 YB
5 N/C N/C
6 2 Left button
7 N/C +5VDC (N/C)
8* 6 and also tie to pin 1 Ground
9 7 Right button
- = 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.

| 2 3 4 5 |
| 6 7 8 9 10 |

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
| 9 7 1 2 | have a pin.
| 5 6 |

Have fun!
