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. -----------------------------<cut here>---------------------------------- Date: 21 Feb 89 03:02:45 GMT From: tektronix!ozvax!tekcsc!jeff@ucbvax.Berkeley.EDU (Jeff Beadles) 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. :-) 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.

Thanks Mickey for reposting Jeffs note on connecting MS mouse to ST
HOWEVER, It appears to me that microsoft has changed their mouse cable
the number of lines and the shape of the connecter are very different
from what you described. (I have the latest MS 400 DPI serial-ps/2 mouse,
did I make a mistake? should I have gotten the bus mouse?)
For example pin 5 on the MS mouse isn't connected to anything in mouse
also on my ST mouse I can press the left button and note resistance on my
volt meter go to zero when I make the approriate connections (between pin 6
and 8) I cann't find any equivalent correlation on the MS mouse, (Though
I haven't tryed every possible iteration). Strangely, resistance does drop
(electricity travels through, me no EE;) through some combinations
of lines but pressing mouse buttons never seems to make any difference.
The MS mouse apears to use only lines 2,3,4,5,7 of an AT (9 pin) serial
connector (and the casing)
Can someone e-mail me the solution to this problem (the correct wiring,
or tell me I goofed and bought the wrong mouse).
by the way I haven't received anything form info-atari16 for about a
week so you better e-mail me directly.
