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. --------------- | 1 | | 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! -Jeff -- Jeff Beadles jeff@onion.pdx.com
