My original mouse seems to be having fits occasionally. After 4 years, I suppose it's time has come.... Well, this crossed my desk a while back. This file is a short description of what it how to buy a Logitech mouse for an Amiga. It worked for me - right now, I'm using a logitech trackman, bus version, on an Amiga 3000. The instructions assume you have some basic soldering/wiring skills. If you don't, you might not want to try this. Whether you do or not, it's your mouse, your Amiga, and your workmanship. If you mess up and destroy something, it's your problem. 1) Obtain a logitech mouse in the bus version. I've only seen the trackman and mouseman in this version; others may or may not be available. Best bet is to just buy the bus mouse from a local store with a good return policy. Just remove the mouse; save everything else for later use. 2) Obtain a femal 9-pin D connector and hood with strain relief for same. I (and several others) spent quite a bit of time trying to find connectors for the logitech mouse, so you could do this without making the mouse unusable on an IBM PC. After a total of probably more than a months time, we found nothing. So you're going to have to cut the cable and put your own connector on it. It looks better that way anyway. 3) Cut the cable short of the mouse, and solder the female D connector on using the following color scheme: Pinout Color Alternate Signal --- ------ --------- ---------------------------- 1 Orange Pink X1 2 Brown Y1 3 Yellow X2 4 Red Y2 5 Violet Blue Middle button 6 Green Left button 7 Black +5 volts 8 White Ground 9 Grey Right button The "Color" is what is in the manual, and what I found in the trackman. The "alternate" is what has been seen in some mice. "Signal" is there for your edification, or for the adventurous to try modifying someone elses bus mouse. Warning: you can muck up anything but pins 7 & 8 (black and white; +5 volts and ground) without damaging anything. Get either of these wrong, and you could fry both ends of the cable. Check it three times. 4) Test it, and see how it works. Turn off your Amiga, plug it in, power up, and try it out. Warning II: Most Amiga mice have plastic around the D connector. This is not true for most parts store hoods. While plugging and unplugging an Amiga mouse from an Amiga with its power on is relatively safe (not recommended, though), a metallic connector can easily short things out, frying your Amiga or the mouse. Be very sure to have your Amiga turned off when plugging or unplugging a mouse with a metallic case. Hints: if the mouse just jiggles around, check pins 2 & 3. If it goes up when it should go down, 1 & 3. Left instead of right, 2 & 4. 5) Shut everything down, put the hood and strain relief on the cable, connect it back up, and enjoy the mouse. 6) Notice that your mouse is now unusable on an IBM PC. Call Logitech customer service, and order a replacment for it. Use the serial number off the mouse you've got, and pay by credit card. 7) When the replacement mouse shows up, drop it in the box with the useless hardware & software that came with your mouse, and return it to the store that purchased it (told you to choose a store with a good return policy). -- Don't tell me how to live my life Mike Meyer Don't tell me what to do mwm@pa.det.com Repression is always brought about decwrl!mwm by people with politics and attitudes li
